My beautiful, big old dog had an operation yesterday - the vet removed a huge 3k tumour from his belly. I picked him up this morning and he was in a terrible state, whimpering. He is usually incredibly stoical so I have never seen him like this. After not eating or drinking water all day he has finally had some plain chicken and been out for a walk. He is still unable to sleep and seems really uncomfortable, whinging constantly.
I don't know what to do. He doesn't usually have attachment issues but he is really ramping it up when I leave the room. He can't sleep in my bed because he can't manage the stairs. He's 12.
Can anyone help me make him more comfortable?
