Does anyone know if eating grass is a sign of anything, such as illness, or a diet lacking in something?
My six-year-old collie mix has always eaten grass, but she seems to be eating a lot more of it at the moment. I'm not sure if all the rain making everywhere very green has something to do with it, but it does seem to have become more tasty to her recently!
Alison Logan, vet, advises…
I know exactly what you mean. My Labbies particularly like lush spring grass which is probably tasty as it is actively growing and fresh, and particularly after a heavy dew. It is often said that a dog brewing a stomach upset will eat grass to purge himself but I have not noticed that with my Labbies… if anything, they are feeling on top form! Often it does all come back up but I have never noticed subsequent illness or malaise. Alternatively, I notice grass in their motions when picking them up, or else help may be needed to remove it from the anus – speaking from experience. I would recommend using a poo bag as a glove, as you always have a poo bag with you when out on a walk but never a disposable glove.
With my vet’s hat on, you ought to consider the possibility of an increased risk to your dog of picking up a lungworm infection with Angiostrongylus vasorum through eating grass which may have slugs and snails on it. Your vet will be able to advise on the most suitable product to use as a preventative.
