Not sure if anyone can offer advice, I have the phone at the ready to ring the vet. He is a six and a half year old Staffie, but he hasn't wee'd or poo'd all day. He did first thing this morning which seemed fine. I have taken him out several times but nothing. He is sitting in the typical Staffie posture but when he tries to walk his back end drops and he ends up shuffling then into a sit/wee position. He has had obstructions in the past. I don't remember it being this bad. He is constantly licking his private bits. I will take him for a short walk see if that help him to relieve himself, if not I will ring the vet.
