Garden plants poisonous to dogs: Check this list
Garden plants poisonous to dogs, Both in many gardens and the field, you can find many toxic plants for dogs. With good weather, our clients and their pets spend more time outside the home, and animals are more likely to contact these plants. In some cases, these are indoor plants that should be avoided in homes with pets. Keep their owners alert, so they know what they are.
Azalea ( Rhododendron spp.)
It is a typical garden flower, widespread and of worldwide distribution. If a dog ingests it, it irritates the mouth and digestive tract with vomiting and diarrhea. In the most severe cases, a drop in blood pressure can occur, and the animal can go into a coma and die.
The poison it contains is called andromedotoxin, and it is found preferentially in the leaves and nectar.
