Hi

My dog has just been sick some potatoes almost undigested, that I gave him two nights ago !!!
Any ideas why this might be ???

If it;s the peel a lot of dogs don't digest it well.  Have to say my Spanish adore them, but I know that a lot of people say for dogs not to hve them

I would stay away from white potatoes,sweet potatoes are much more nutritious, and make sure to mash them thoroughly so they can be digested properly.I've read that potatoes tend to sit in the gut in lumps of starch that cant be digested and slow the whole process down,which sounds like what may have happened to your dog.

Were the potatoes cooked? Whole/unmashed veggies cooked or raw tend to come out the same way they went in.
