Can definately see some kink or lump on his spine. Has this just appeared or did he have it when you got him? Have you had him long? If it's just appeared then it could be the result of an injury say a fall onto something heavy. I would take him to the vet hun. He's very cute I must say.
thanks i know he looked a little unsteady on his legs when i had him just under a week ago but now he has had a good feed he looks like this only when he walks sometimes it looks bad others he seems fine he runs and swims fine and is still eating fine he seems fine in himself and even lies flat under rocks and under the log i have in there i might keep a close eye on him for a couple of days and if it gets worse or he seems to be in any pain them up the vets we go fingers crossed i know people are telling me to go straight to vets but trust me is you was to watch him there is nothink wrong ( apart from the walk )
