What symptoms can my dog get after eating toxic plants?

Unfortunately, there are many plants that are toxic to dogs. The symptoms your dog may develop can vary widely, from gastrointestinal issues (vomiting and diarrhea) to skin irritation. Sometimes other symptoms occur, such as hyperactivity, tremors, dilated pupils, paralysis symptoms, heart rhythm disturbances, and shortness of breath. The severity of symptoms often depends on the amount of plant your dog has eaten. The toxicity of the plant also plays a major role.

In this blog, we’ll try to distinguish between extremely toxic plants, toxic garden plants, and toxic houseplants.
