Thanks very much for the link to that site - it has some really good info. on it.
Garlic? Hmm - I Gargled - sorry, Googled: is garlic poisonous to dogs?
All the posts, from animals associations and vets seem to warn against giving dogs garlic - it is, after all, a member of the onion family.
From what I’ve read, more and more foods have been added to the list during the last five years. By the way, just what are Macadamia nuts, I wonder - is there a place called Macadamia?
All the Best
