Many dog owners don't consider that harmless little house and garden plants may be a potential source of danger to your dog or puppy. Usually poisonous plants are more deadly to small puppies, but some plants, even in small amounts, can be toxic to dogs of any size. By taking the time to understand the various plants and their levels of toxicity for dogs you can avoid costly vet bills and even more serious conditions.

Depending on the type of plant either the leaves, stems, bark, roots or fruit can be toxic. Some plants are only toxic at various times in their growth stage whereas others are always poisonous. For information on each type of plant the internet, your vet, or even a plant and gardening book is great resource.
