Hello and welcome to Deckland. He is a very big and beautiful german sheppard.
One of the ailments they are famous for is called CDRM. This means they get very weak in thier hind. So Decland has been suspected of this disease and sent for physio.
Although this is a progressive disease and does get worse with time, there are things that can be done to slow it down.
The physio here is designed to keep the nerves fireing so they remain healthy for longer. Its also important this is managed correctly, as fatigue and over work can do the opposite and make the problem worse, faster.
So we have set Deckland up with a sensible and achievable home regime.
Keep up the good work mum, dad and Decland.
