I have an Italian greyhound 4 month old puppy who is severely underweight due to illness. The vet is involved and we are finally on the right track: he is gaining weight and the sickness and diahorea seems to have stopped. The problem is he feels the cold. He has a fleece jumper and a very thick fluffy bed and blanket in side a crate with a cover on to stop drafts but he is still cold. Obviously it’s getting cold outside to although we limit his outside time due to his weight and he is currently not going on walks (vets advice). Anyone got any ideas?
