Keep Your Dog Away From Onions

Onions of any variety are extremely dangerous for dogs. This includes all parts of the onion plant, including the leaves, roots, and juice. Other plants in the allium family, including leeks, shallots, and garlic, are also dangerous to dogs.

Onions contain N-propyl disulfide, a compound that can cause your dog to suffer from a breakdown of red blood cells, causing anemia. If you think your dog might have eaten onions, look out for lethargy, weakness, decreased appetite, reddish urine, and elevated heart rate.

If your dog eats onions or other alliums, get them to a vet immediately. Your dog may require a blood transfusion. You may also want to check the labels of any cooked meals or packaged snack foods you want to feed your dog. If those foods contain onions, don’t let your dog touch them.

Sweet Foods Can Be Dangerous

This doesn’t just include chocolate. Most candy brands contain xylitol, a sugar-free sweetener that is harmless for humans but deadly for dogs. Xylitol can also be found in chewing gum or some baked goods. You’ll want to check the nutrition label before feeding your dog any of those things, but it’s best to err on the side of caution.

Symptoms of xylitol consumption include vomiting, weakness, lethargy, or seizures. These symptoms will generally appear within half an hour of consumption. If your dog gets into your kid’s Halloween candy or consumes something else with xylitol, you’ll want to see a vet immediately. Xylitol can cause your dog to suffer a rapid drop in blood sugar, which can lead to liver failure.

Don’t Let Your Dog Near Avocados

Avocados contain persin, which is toxic to several animal species. The pulp of the avocado only contains small amounts of persin. How dangerous this amount may be will vary from dog to dog. However, a sensitive dog may develop pancreatitis from even small amounts of avocado. In general, it’s best to keep your dog away from avocados.

If your dog does eat an avocado pulp, keep an eye on them for the rest of the day. They may be fine, but you might want to take them to a vet if you notice vomiting, diarrhea, or signs of intestinal discomfort.

The pit of the avocado, on the other hand, can be extremely dangerous to dogs. Small pits might become a choking hazard or an intestinal blockage if your dog swallows it.

Give Your Dog Raw Bones, Not Cooked Ones

Your dog may enjoy gnawing on bones. However, if you do give your dog bones, you’ll want to make sure they only get raw ones. After being cooked, bones become softer and may splinter if your dog chews on them. This can be dangerous if your dog swallows a piece of bone. Small or thin bones may be dangerous for the same reasons. Bone splinters, if swallowed, can damage your dog’s mouth as well as their gastrointestinal tract.

Tomatoes Can Be Dangerous to Dogs

Ripe tomatoes should be perfectly safe for your dog to eat. Tomato leaves, on the other hand, are a different story. The stems and leaves of the tomato plant contain solanine, as does the unripe tomato fruit. Solanine can cause your dog to suffer gastrointestinal upset, heart problems, loss of coordination, weakness, and seizures.

If you think your dog has solanine poisoning, take them to the vet quickly. Most dogs will recover from solanine poisoning with proper treatment. Nevertheless, don’t let your dog eat green tomatoes. If you’ve got tomato plants in the yard or in the house, make sure your dog stays away from them.
