The Holidays are so much fun, but can be a hectic time for the family. Lots of food, decorations, people visiting, and possibly more time for our pets to be home alone while we are out making the rounds. Our pets are family, and we want them to enjoy the Holiday season as much as we do. However, there are some things we need to be aware of this time of year to help keep our pets safe during this busy period. The following is certainly not a complete list. If your pet has ingested something and you are concerned (especially if the pet is showing signs of feeling unwell), call the Pet Poison Helpline at 1800-213-6680. They do charge a small fee for their assistance, which includes case follow-ups (an is much cheaper than an emergency bill, if that can be avoided!).
• Foods containing grapes, raisins, and currants (such as fruit cakes, breads, and cookies). These can result in kidney failure in dogs. The actual toxic dosage is unknown and seems to vary greatly from pet to pet.
• Alcohol. Most pet owners know not to give alcoholic drinks to their pets; however, alcohol can be found in other places, such as rum-soaked cake and in raw bread dough containing yeast. Ingestion of alcohol by your pet can cause signs including ataxia (difficulty walking), disorientation, changes in blood pressure, and abnormal blood sugar levels. In addition to the risks associated with alcohol ingestion, raw dough can expand in your pet’s stomach and can result in bloat, which may be life-threatening.
• Chocolate and cocoa contain theobromine, a chemical similar to caffeine. Ingestion in small amounts may cause vomiting and diarrhea, with cardiovascular and neurologic changes possible with large ingestions. The amount of theobromine present in chocolate depends on the type. White chocolate and milk chocolate contain the lowest amounts of theobromine, while unsweetened and baker’s chocolates contain high amounts of theobromine. The specific risk to your pet depends on the amount ingested, the type of chocolate, and the size of your pet. Pancreatitis (inflammation of the pancreas) is a concern even in cases where poisoning is not expected.
• Leftover fatty, meat scraps can produce severe inflammation of the pancreas (pancreatitis), leading to abdominal pain, vomiting, and bloody diarrhea.
• Many sugar-free gums, candies, and baked goods contain xylitol, a natural sweetener that is toxic to dogs. Ingestion of xylitol may result in a life-threatening decrease in blood sugar as well as liver failure.
• Ma*****na, specifically the THC chemical, is toxic to pets. Animals that have been exposed to edibles, or even second-hand smoke, should be taken to a veterinarian for an examination and/or for supportive care. Common signs that owners may notice include inactivity, incoordination, dilated pupils, increased sensitivity to motion, sound, or touch, hypersalivation, and urinary incontinence.
• Batteries in toys, greeting cards, electronic devices, flameless candles, and remote controls can cause serious injury if swallowed. Internal burns can occur in a very short time.
• Water from Christmas tree stands can contain bacteria and chemicals. Swallowing the water can cause stomach upset and diarrhea, even if the ingredients aren't poisonous.
• Many types of tree and home decorations can also pose a risk. Pets can choke on tinsel, ribbons, and Christmas tree needles. The latter can also cause linear foreign bodies if ingested. Toss the tinsel altogether, or place it in a safe area out of the reach of curious pets.
• Poinsettia is not actually a deadly plant; the sap from poinsettia plants can be very irritating. Pets who chew on poinsettia can develop skin rashes and mouth irritation. If they swallow the plant, they could have stomach upset and discomfort.
• Holly leaves are prickly and can cause injury if a pet tries to eat them. Holly berries can be poisonous; they easily dry up and fall onto the floor, where pets (and children) can find them.
• Many human medicines are poisonous to pets. For example, small amounts of over-the-counter pain relievers can be fatal to cats and dogs. Even if your own medicines are stored safely, be aware that visitors may have medicines in their purses or suitcases. Provide a place for these things to be stored safely, out of sight and reach of pets (and children).
• Ice melts are commonly used around entryways and sidewalks, and the containers that are filled with these products are often left within a pet’s reach. There are numerous formulations available, many of which contain salt (sodium chloride), and small exposures typically lead to stomach upset and dermal and paw pad irritation. Larger ingestions may quickly cause salt poisoning, which can result in a rapid onset of vomiting, excessive thirst, and seizures. If your pet has consumed any amount of ice melt, it is important to call for help.
• Salt dough ornaments are a fun way to spend time together and focus on creating joy. As beautiful and memorable as these keepsakes may be, they can also pose a serious threat to the dogs endlessly looking for something to munch. As few as 1-2 ornaments could make your dog very sick. There is enough salt in the ornament that your dog could easily become trembly and stumble from salt poisoning. The baked ornaments can also be very difficult to pass, causing either pain or obstruction. If you do choose to make salt dough ornaments, be sure to keep pets out of the area while the crafts are being made, place the ornaments in a high location so pets can’t get them off a counter while they are drying, and then hang them on a tall, sturdy branch to avoid them falling off the tree.
With careful monitoring and planning, everyone in the family can have a safe Holiday with no unplanned trips to the emergency clinic!
