23 Common Plants Poisonous to Pets

Pet owners know that dogs and cats often have a penchant for eating strange things. Cats often gravitate toward plastic or wool, and many a dog will chew on whatever it can get its chops around. And then there are plants.

In order to prevent poisoning by cut flowers or house plants, avoid placing toxic ones in your home where pets may be able to access them. Or better yet, avoid buying flowers and plants that are known to be toxic. Outside is trickier, especially if your dog or cat has a wide range to roam.

The only other thing to do is to watch your dog’s behavior when outside, and try to prevent them from munching on vegetation unless you know it is harmless. When you see symptoms such as vomiting, diarrhea, difficult breathing, abnormal urine, salivation, weakness, and any other abnormal condition, take your pet to the veterinarian because he may be poisoned
