Hi everyone,

There might be a previous posting on this one, my search facility to playing up for some reason and I'd really appreciate your opinions.

A colleague of mine has an arthritic dog and he feeds Burns.  Whilst his dog has been on Burns, he will eat grass but is never sick.  Following a visit to his vet, he changed his dog's food to a prescription diet; Hills SP JD which I think is a new one on the market.  Since his dog was converted to this food he still eats grass but is now sick.

I thought it was the toxins in the food that was causing the sickness and told him to put his dog back on Burns.  Again you hear many different opinions. Even some that say that dogs are sick due to a eating a particular type of grass or a particular type of microbe that may be on the grass.  

Has anyone else had a similar experience when changing diets?

My boys have always eaten grass but they are never sick because of it.

What reason did the vet put him on hills ?  I would have personally kept him on Burns :)

His dog has Hip Dysphasia and this Hills Diet has been formulated with omega 3 fatty acids.  Designed to help the joints.

Quite a while ago, before all this knowledge about pet food companies came to light, I fed my dogs Eukanuba which I believe has been relabeled to Iams.   My dogs would nibble on grass in the spring and they were always sick.  It became a regular thing that when they ate grass we expected them to be sick.  Since I changed to Burns, they still nibble on the long blades of spring grass but are never sick.  That's what led me to believe it was more about the food they were eating than it was about the grass.

Personally I think that being sick after eating grass has more to do with it getting stuck and causing irritation. My cats have the same problem and one even ended up at the emergency vet because she got some grass in her wind pipe! Mind you the vet told us she was fine and wanted to send her home until we pointed out her less than salmon pink gums :rolleyes:
