Xylitol is a commonly used sugar substitute that is as sweet as sugar with only two-thirds its calories. It is frequently found in sugar-free gum, candy, baked goods, desserts, and toothpaste. In people, xylitol is a safe compound with few associated side effects however it may have significant adverse effects in dogs. The ingestion of xylitol has been associated with a severe drop in blood sugar (hypoglycemia) and acute liver failure.
Signs of low blood sugar have been noted as soon as 30 to 60 minutes after ingestion as it is rapidly and almost completely absorbed! Why is there such a drop in blood sugar? Xylitol causes a rapid, significant increase in insulin secretion in dogs and insulin causes the blood sugar to decrease.
Acute liver failure can also become evident up to 72 hours after ingestion. Although there are two thoughts as to how this occurs it is not exactly known how this happens. It is believed that products produced by the liver when breaking down the xylitol cause severe damage. One toxic by-product depletes the liver cells of their energy source while the other reactive product damages the cell membranes, both leading to cell death.
If liver injury occurs after Xylitol ingestion the prognosis is unfortunately poor. A study revealed that 63% of dogs that ate xylitol containing products died despite aggressive medical management. Interestingly, the dose ingested does not equal whether one pet or another will develop liver failure.
If you noticed your pet eat something they weren’t supposed to, look at the ingredients. If xylitol is listed on the product bring the product packaging and your dog to the veterinarian immediately. If your dog recently ate a xylitol containing product your veterinarian can induce vomiting to try and get out as much of the product as possible. The vomiting may not be effective if ingestion was not within the past 30 to 60 minutes as xylitol is quickly absorbed by the body.
Signs of xylitol toxicosis include vomiting, diarrhea, a drunken gait, coma, and seizures. Sings of low blood sugar can occur within 30-60 minutes and if liver failure occurs signs are usually evident within 12 to 72 hours of ingestion.
Dogs have a better prognosis if improvements in blood work abnormalities related to the liver and stabilization of the blood sugar levels occur as well as lack of progression to acute liver failure within 3 days of ingestion.
It is therefore important to make sure that your xylitol containing products be kept away from your pets. It only takes a quick second for your dog to jump on the counter and eat the package of sugar free gum you just purchased. If this occurs call your vet immediately and don’t forget the package on your way out.

Performing a brief monthly at-home exam on your pet
Just as physicians recommend monthly self-examinations for men and women (whether we do perform them or not is another story), I recommend a brief at-home monthly check-up of your pets. This of course DOES NOT replace the more thorough 6-12 month check-ups recommended by your veterinarian (more frequently if your pet has a health problem). The purpose of these brief at home exams is to identify changes in your pet that may require you to see your veterinarian sooner than the previously scheduled check-up.
A great time to do this is before you apply the monthly flea/tick/heartworm preventative medication and it should only takes a few minutes. The more routinely you perform this the easier it will be for you to note when changes do occur.
Just as I start my exams in the office, step back for a moment and just watch your pet. Do they seem to breathing comfortably? Do they appear too thin or overweight? Do they have trouble laying down and getting up? This is a good time to go over and answer the important questions your veterinarian will ask (see previous blog post “10 important questions your veterinarian will ask that you should be prepared to answer”).
I then recommend starting at the face and working your way to the tail. Observe for any discharge or redness of the nose, eyes or ears. If discharge is seen, note which side is affected and the amount and color of the discharge.
Next, if your pet allows, gently lift the lip on each side and note any tartar on the teeth, broken or discolored teeth or changes to the gum color. Healthy gums should be a nice pink color. Bright red gums along the border of tartar covered teeth may signify gingivitis. Some pets have pigmented gums and these changes may be difficult to assess. If you notice pale, blue/purple or yellow gums it is best to call your veterinarian and have your pet assessed further as they may have a serious medical condition.
Next, move your hands along the neck to the shoulders, down each front leg and back up and down the rest of the chest and abdomen finally reaching the back legs. As you do this you should be feeling for any lumps, bumps or painful areas. Three areas to check as you move from head to tail are at the end of the jaw just below the ears, in front of the shoulders, and behind the knees. Major lymph nodes are located in these areas and any changes to their size may indicate inflammation, infection or cancer. You can ask your veterinarian to demonstrate where you should be feeling during your next visit.
If lumps are encountered they are most likely lipomas or "fatty growths" that don’t cause a problem unless they get too large and infiltrate adjacent areas BUT lumps that look and feel like "fatty growths" can also be dangerous cancerous lumps. The only way to tell the difference is to have your veterinarian sample them. This is easily done as we poke the lumps with a needle and apply the cells on a slide (fine needle aspirate). Your veterinarian may look at it under the microscope in their office or send it to the lab so a pathologist can analyze the cells. Obtaining this aspirate is not 100% as only very few cells are sampled, but is a good start in helping decide if this lump should be removed immediately or if it is ok to monitor it for changes in size and appearance. Your veterinarian will note the size and location of the lump in the record to keep track of it during future visits. Sometimes depending on the location, feel and look of the lump it may be recommended to remove a piece of the lump and send it to the pathologist instead of performing an aspirate or after an aspirate.
Once you reach the tail, again if your pet allows it, lift the tail and examine for any discharge, nodules or uneven, bumpy areas around the anus. Tumors involving the anal glands can occur and go unnoticed until it is so large that your pet has trouble defecating and by that time it has most likely spread. In female dogs you can monitor for any discharge from the vulva.
Finally, if your pet is good about laying on its side or back, examine the hairless areas of the belly for any rashes, redness, fleas or mammary growths. Run your hands along their bellies and note any lumps and bumps. In male dogs this is a good time to notice any discharge from the penis.
This simple and quick exam will help you identify any possible changes to your pet’s health earlier, instead of waiting months for the next scheduled exam. Recognizing these changes early may save your pets life, allow for a possible cure or at least be able to start important medications before the disease becomes too advanced. It also helps your pets get used to a part of the more thorough examination that your veterinarian will perform. As always, if you have any concerns about your pet, please call your veterinarian first for further advice before ignoring a problem, misdiagnosing a problem or self-medicating your pet as you may be causing more harm than good!

The small but dangerous Foxtail (Grass Awn)
At first look you think, what’s the big deal with this little piece of a plant? (Foxtail picture: www.twitpic.com/21bbl7) Well, if your pet has had an encounter with a foxtail you definitely know how much trouble they can cause!
Most of the time they get into your pet’s ears, nose or eyes and with a little sedation your veterinarian can usually remove them easily. Sometimes they can bury into the skin and end up embedded (usually within a paw) causing inflammation, infection and PAIN! (*Viewer discretion* Picture from a few days ago of foxtail being removed from a paw: www.twitpic.com/21bbzu).
Last week I saw a little dog that was squinting and kept pawing at his eye. It was very inflamed and watery. I put some local anesthesia in his eye, probed around and noticed a thin tan colored object poking under the eyelid. I began to remove it and it kept going and going and going …It was the longest foxtail I have removed! Although it was the longest foxtail I have removed I almost missed it and was amazed as to how it made its way under the eyelid!
Unfortunately for pets, the little barbs on foxtails were designed to help them bury themselves and travel one-way deep into tissues, sometimes traveling internally to a body cavity and setting up an infection. In one unfortunate cat, the foxtail managed to burrow through the skin and travel to its heart causing a deadly infection! (*Viewer discretion* Picture of heart with a foxtail within it: www.twitpic.com/21bcvk and www.twitpic.com/21bdm0).
Signs that a foxtail may be causing trouble include sudden onset of squinting and/or discharge from an eye, pawing at the face, shaking of the head, pawing at an ear, constant sneezing, nasal discharge, limping or constant licking of a paw. If you notice these signs it’s a good idea to make an appointment with your pet’s veterinarian, especially if you find yourself removing foxtails from your pet’s coat.
If your cats or dogs go outdoors, especially during the summer and fall seasons when grasses begin to dry, be sure to brush them daily and remove all foxtails that you find. Always inspect their ears and paws as they can hide between the toes!

Pet Pool Dangers
I'm sure there are many dog owners out there with pools or those that take their dogs to their friends house who own a pool. Well, just as you have to be careful with kids and pools, you MUST keep a close eye on your dogs as well.
But all dogs know how to swim right? Why would they have trouble if they fell in a swimming pool? Well, for the most part they all know how to swim. The danger actually comes when the pool has steep sides and does not have a shallow area or easy access to get out. This is of most concern in small breed dogs and puppies, they get tired, cant get out and drown.
For those that must know, when water is inhaled the natural coating of the lung surface (surfactant) is compromised and it allows for the air sacs within the lungs (alveoli) to collapse. Collpased lung tissue can't replenish oxygen in your blood or get rid of carbon dioxide that has built up. Many severe metabolic changes occur in the body. Inflammation of the lungs can also occur and the tissue becomes leaky resulting in more fluid building in the lung (edema) and acute respiratory distress syndrome (ARDS).
Most pool accidents are witnessed but some are not although it is easy to suspect when you find your dog soaking wet and having trouble breathing. Sometimes coughing is noted, they can be in shock, have changes to their behavior and they can even be in a coma. A recent study of fresh water drowning revealed that level of consciousness at admission was not associated with outcome and showed full recovery even of animals presenting in a coma. So call your veterinarian immediately and take your pet in!
Depending on your dogs condition they may be too unstable to do further tests and must be placed in oxygen immediately, sometimes a ventilator is needed if they are not breathing on their own. If stable enough blood samples to check metabolic status and chest radiographs will be obtained. If your pet seems ok, it is recommended to keep your pet hospitalized for at least 24 hours of monitoring as things may worsen and the initial tests may not show the real extent of the damage.
Not too long ago I had the first pool incident of the year. Although the owner did not observe the incident, she found her new puppy wet and having difficulty breathing. Chest radiographs were consistent with what is expected in a near-drowning. He was placed in an oxygen cage as part of his treatment and luckily survived. I saw him just last week to finish his vaccine series and he was doing great!
I had one client bring her puppy in for vaccines and told me that her puppy was playing and fell in the pool. She was swimming around but the tiny little thing couldn't get out. Luckily the owner was there and took her out of the pool. To avoid this, I recommend that my clients who own pools purchase a floating ramp that they can connect at one end of the pool and teach their dog what it is and how to use it. It can save their life, especially for the little ones!
What about just keeping the backyard door closed? Well some have doggie doors for obvious reasons, sometimes the phone rings and we stop watching our pets (and kids), the pool party conversation becomes very interesting or sometimes we don't even realize someone followed us out and we close the door on the way in. I have left my poor dog out only to wonder why the house was so quiet and who was barking outside!
So when it comes to pools be very careful with your dogs access to it when unsupervised and I recommend you make sure they can get out or make adjustments so that they can! Nothing is more sad than an accident that could have been prevented!

Heatstroke
Heatstroke causes a severe rise in your pet’s body temperature and occurs due to elevated temperatures in the environment or from performance of strenuous activity. Unfortunately the summer time allows for a combination of the two and an increase in the cases of heatstroke. It can happen as quickly as 30 minutes and is worse in places with increases in humidity, especially if there is no access to shade or breaks to rest and cool down.
Dogs cool off mostly by panting as air contacts the mucous membranes of the upper airways and allow evaporative cooling to occur. With high humidity, the evaporative cooling mechanism is not as effective. Short nosed breeds such as Bull Dogs that suffer from brachiocephalic syndrome (partially opened nares or long soft palates among other things) or dogs suffering from other upper airway problems (such as collapsing tracheas or laryngeal paralysis) are at greater risk for developing heat stroke as their main cooling mechanism is not in top shape.
Signs of heat stroke can include excessive panting, collapse, seizures, excessive salivation, vomiting, and diarrhea and occur after exercising on a hot day or being left in a car even if the windows are cracked.
Permanent and life-threatening damage to organs such as the kidneys, liver, intestines and brain can occur if not treated immediately.
If you suspect your pet is suffering from heat stroke move them into a shaded area, wet them down with COOL water and call your veterinarian immediately to let them know you are on your way. Using COLD water will only make things worse as the outer blood vessels which are helping to cool your pet down will close off. Fans or air conditioning will also help with cooling.
Your veterinarian may need to obtain baseline blood work to evaluate for organ damage, place an IV catheter and administer fluids and other medications as well as hospitalize and monitor your pet. OVERCOOLING can be more harmful than helpful and this is why it is recommended to start the cooling process and go to your veterinarian immediately for careful monitoring and adjustment to treatments as necessary.
Studies reveal that pets that present to their veterinarian soon after are more likely to survive than animals seen later. Pets that survive the first 24-48 hours of hospitalization generally do well.
I have seen cases of heatstroke in dogs left in a car WITH THE WINDOWS OPEN for only a couple of minutes, dogs going about their usual outside play on a hotter than normal day and dogs taken on long runs and hikes.
Be safe this summer and remember that if you are enjoying a nice day out with your pets to allow rest breaks, access to shaded areas, plenty of water and know when to stop! If you have any concerns at all see your veterinarian, it’s always better (and cheaper) to be on the safe side!
