Sorry this is a bit long!
I have 21 month old male Dobermann who weighs 42kg. For the last 3 or so days he has been limping on and off on his left hind leg. Upon waking in the morning the limp is there only very very slightly. Following our morning routine (walk, breakfast, training, play etc) he'll then nap.
Upon waking after this sleep, he'll stand with no problem but he'll be holding his left leg high up into the air and will walk like that for about a minute. As he hops around he'll gradually be lowering the leg to the ground, and will then walk/run around completely normal. He makes no vocal noises of being in pain but it does look bad to see.
A bit later we have a late afternoon/early evening walk and the same thing will happen again. Sometimes he'll only have been laying down for 30 seconds whilst I take my coat off after we get back and the limp will be just as bad as if he's been laying down for an hour and a half.
This same thing happened maybe 3 weeks ago in the same leg. I cut down a lot of the off lead time he has on the second walk and he had seemed to improve. I've kept this the same so am unsure why it's happened again.
We've also had this in the past with his left front leg (exactly same symptoms) on and off, the first time being when he was about 5 months old (that first time it happened he had tripped over his own legs when running and roly-polyed down the garden though). He's had his legs checked at the vets and they can't feel anything wrong, everything is moving properly and he shows no pain. Up and about he moves normally when walking and running (except once when the limp has started during running) and our ringcraft trainer has not noticed any abnormal movement.
I keep coming across things about hip dysplasia and am worried. He did charge around a lot as a youngster and now I'm wondering if we have caused something. We got him really focused on toys, chasing balls etc to tire him out (as well as short training sessions) as the biting was almost intolerable (we've had 2 dobermanns before but he has been an entirely different story!). It has always been difficult to find ways to occupy him. If he's awake then he wants to be up and about doing something. He suffers from colitis so we've been very limited when it comes to kongs, bones, anything edible that might take him some time to get through really.
Anyone have any suggestions as to what this limping might be?
