Vaping Product Hazardous to Your Pet!

Electronic cigarettes such as Vapes and Juuls have gained popularity as a healthier and potentially less expensive alternative to cigarettes, but for our pets, it could pose a greater risk than the classic tobacco.

The toxic compound here is nicotine, which is extracted from tobacco as a highly-concentrated liquid that is then added to some chemicals of negligible toxicity to create e-juice. E-cigarettes contain a cartridge for e-juice that, when heated, becomes the vapor users inhale.

It is this juice (also known as e-liquid or vaping liquid) that can pose such a severe threat to our pets. While a full cartridge of e-juice in a vaping device could contain up to 36 mg of nicotine, a single 30mL (average-sized) bottle of the liquid, at 36mg/mL, will contain 1080 mg of nicotine. To put this in perspective, just 0.5 mg per pound of body weight is enough for cats and dogs to show clinical signs of nicotine poisoning, with lethality starting at 20mg for the smaller animals.

It is important to remain careful if you use e-cigarettes to keep both the e-juice and the vaping device out of your pet’s reach, but also away from the edges of tables or countertops. Beyond the danger of ingestion, nicotine can also be absorbed into your pet’s body through their skin. A spill on their back or beneath their paw could be just as hazardous as lapping it up off the floor.

Because the nicotine in the vaping liquid has already been extracted from the tobacco, it could take as few as 15 minutes for signs of poisoning to begin, whereas they may not begin for a few hours if it had been a cigarette with tobacco that still has to release the nicotine. These symptoms include rapid heart rate, vomiting, muscle tremors and, in the worst cases, stupor, collapse, or coma.

If you suspect your pet has been exposed to this e-juice, it is important that you call Animal Poison Control at (888) 486-4435 and get your pet to a hospital as soon as possible. You can contact our office by calling (925) 443-6000, but if the emergency takes place outside our normal business hours, there is a list on our website of after-hours emergency hospitals to reach out to.

Remember to stay safe and aware when using products that could pose a threat to your furry friends!

Foxtails: Tiny Seeds, Big Problems

Foxtails: Tiny Seeds, Big Problems

Foxtails are one of the more serious pet hazards in our area: not only can they work their way into any part of your dog or cat, but they’re very hard to find in a pet’s fur. They like to get around, too—a foxtail in the nose can migrate to the brain and one in the skin can eventually make its way to a lung.

To decrease exposure to foxtails, try to keep your pet out of tall grasses and remove all foxtail plants from your yard. If your pets are outside frequently, brush them regularly and check for foxtails over their entire body, paying special attention to your pets’ ears, mouth, nose, between their toes and around the base of their tail.

While you can use tweezers to remove foxtails you find on your pet right after attachment, a visit to the veterinarian is recommended if you notice the following symptoms:

  • Constant licking of an area, especially feet or genitals
  • Limping or swelling of a foot
  • Shaking the head, tilting it to one side or scratching incessantly
  • Redness, discharge, swelling, pawing or squinting of the eyes
  • Frequent or intense sneezing, or nasal discharge

At Del Valle Pet Hospital, we encourage you to ask us any questions you have about foxtails and how they affect your pet, especially around this time of the year. For more information, or if you notice any of the above symptoms, please contact us at 925-443-6000 or reach out online.

Rattlesnake Season is Here

Rattlesnake Season is Here

As we enter summer and you spend more time outdoors with your pets, remember to look out for rattlesnakes. Like all cold-blooded animals, rattlesnakes are more active in the hotter seasons. They love to bask in the sun, so there’s a good chance you’ll come across one when hiking, camping or walking in our area.

To lower the risk these bites can pose to pets, Del Valle Pet Hospital highly recommends having dogs vaccinated against rattlesnake venom.

Rattlesnake venom is extremely dangerous to pets because it causes excessive swelling and death of the tissue surrounding the bite wound. Because the vaccine can only reduce the severity of symptoms, bites should always be treated immediately at our hospital or, if we are closed, our closest emergency vet hospitals are:

Other things to consider regarding outdoor pet care in our area include remaining on designated paths and to always remember to keep an eye (and an ear!) out for rattlesnakes. And of course, always keep pets leashed and out of brush.

For more information on rattlesnake venom and your pet, or if you’d like to schedule your pet’s rattlesnake vaccine, please contact us at 925-443-6000 or book online today.

Flea & Tick Season . . . is Coming

Flea & Tick Season . . . is Coming

Your pets are much more likely to encounter fleas and ticks around this time of the year. Don’t overlook the problems these pests cause: fleas can trigger dermatitis and hot spots and one tick bite can transmit numerous dangerous diseases.

Your pets are much more likely to encounter fleas and ticks around this time of the year. Don’t overlook the problems these pests cause: fleas can trigger dermatitis and hot spots and one tick bite can transmit numerous dangerous diseases.

It’s always a good idea to constantly check your pets for fleas and ticks on a daily basis. This can be done while you are playing with your best friend or grooming them. Although fleas and ticks can be anywhere on your pet’s body, they prefer posting up near the head, ears, neck and paws. You can spot evidence of fleas if you notice little black specks that resemble pepper or bits of dirt.

Preventive medications are the best way to keep fleas and ticks away from your pets. At Del Valle Pet Hospital, we have a variety of products for dogs and cats, which will help rid your pet of these nuisances.

If you’re not sure which preventive medications are right for your pets or would like to discuss a proper course of action, we highly encourage you to schedule an appointment with us today by calling 925-443-6000 or scheduling online.

Together we can eliminate these freeloading pests!

Keep Your Pets Safe This Paw-liday!

Keep Your Pets Safe This Paw-Liday

The winter holidays are fun for us humans, but our parties, decorations, and festive foods can put our pets at risk! Here are a few tips for keeping your animal companion safe this season:

• Skip the tinsel if you have cats. They’re very attracted to shiny objects and you don’t want them ingesting tinsel.

• Keep pets away from holly, mistletoe, poinsettias and lilies, which are toxic to animals.

• Secure your tree to a doorway or strong drapery pole with fishing line to keep it from falling over if your dog bumps it or your cat tries to climb it.

• Chocolate, raisins, grapes, onions, currants, macadamia nuts and walnuts are all on the naughty list for pets as these foods can make them seriously ill. Also, beware xylitol (an artificial sweetener found in chewing gum, candy and peanut butter) which can cause illness and even death.

• Put your pet in another room with toys and a bed when having a party or large gathering. This way your dog, and especially your cat, will be less stressed.
