Dog Health Notes >

Which plants are poisonous to dogs?

These hints and tips has been kindly supplied by Patsy Parry of Able Trainers, and is especially of interest during the summer months or when you're working clearing up in the garden, or when you've just got a puppy and they are exploring lots of things in the garden.


Patsy says ......
I cannot stress how important it is to watch what your puppy or dog is eating when you are all in the garden. Puppies especially explore the environment with their mouth.

( A wee note from Pawsability .... to be safe ....if your gardening skills are anything like mine you may not even be able to recognise half of these...... simply don't let your dog or puppy eat or chew ANYTHING in the garden!)

All evergreen plants in the garden can be toxic to dogs, and usually your dog will leave them alone, but be careful if you are in the garden cutting back your plants and the dog starts chewing on a recently cut branch.
