Poisonous Plants for Dogs and Cats to Avoid
Is your pet safe in your garden?

Running through the grass on a warm Summer’s day is a pet’s paradise. After being stuck inside all Winter, your furry friend is finally able to stretch their legs and explore the outdoors. But sometimes, this freedom can be dangerous to their health. Plants in particular can pose a major risk. Certain plants, both indoor and outdoor, can actually be poisonous to cats and dogs.

So, how can you protect your pet from these toxins?

With basic knowledge of preventative healthcare for pets, you can learn which plants might make your animal sick. This way, you can remove them from your yard and home. The following are some of the most common plants that are actually dangerous to your cat or dog.

  • Mushrooms: You would not pick a mushroom off the ground and eat it, but your pet does not have this same sense. For pets, symptoms of mushroom poisoning include vomiting, abdominal pain, weakness, diarrhea, uncoordinated movements, and even a coma. If your pet does eat a mushroom, pick a sample of the fungus and put it in a plastic bag. This way, your vet can identify whether it is dangerous or not.

  • Daffodils: These pretty flowers may pop up in your garden every spring, but they can be toxic if your pet takes a curious bite. These plants cause symptoms including vomiting, diarrhea, tremors, and cardiac arrhythmias. If you have a dog or an outdoor cat, it might be best to plant different flowers.

  • Marijuana: If you enjoy marijuana from time to time, keep it away from your pet. The THC inside the plant can be poisonous to animals. If they ingest the plant directly, or eat a food that contains marijuana, they can experience low heart rate, respiratory depression, low blood pressure, lethargy, coma, and seizures. Even secondhand smoke can cause these symptoms, so ingest with care.
