Mongrel with brain problem

The rescuer of a mongrel came online in another forum asking for help regarding the dog's problem. The rescued dog, now 11 months, was diagnosed with a brain problem - a condition that causes him to crawl rather than walk properly and the vet was not confident that the dog would recover. He is the only dog in the batch that has this brain problem. His mother and siblings have been successfully rehomed but no one would want to take in this 'handicapped' dog. A few months earlier, the dog could get up once in a while and walked a few steps but now the rescuer said that his condition has deteriorated to the extent that he can't even stand up.

I visited the rescuer and dog last evening and observed the following.

~ He was very alert, barked at me (stranger). Seemed quite a happy dog when the rescuer was at his side. He wagged his tail vigorously. I can't get much of his mental picture because I was there for a short while.
~ Size and weight – OK for his size; quite lean and muscular.
~ Not sterilized yet
~ He got along well with his 2 little female companions.
~ A bit wary of me when I approached him yet he did not bite me when I stretched out my hand to let him sniff.
~ He struggled a lot on the floor causing him to have sores on his hind legs and paws. – the paws would bleed whenever the rescuer tried to clean them. This was due to his inability to stand up to urinate and pass motion. The paws were very sensitive to touch and the dog would want to bite the person who attempts to clean the sore areas.
~ Both front legs seemed overstretched. Can't seem to bend at the joints – occasionally the paws would turn inwards.
~ Lately a soft watery lump developed on the front left leg. Kind of a swelling but no redness or pain. Probably the dog must have knocked himself against the furniture many times during his attempts to move about.
~ The rescuer has laid the whole room with pieces of foam joined together, hoping this would cut down the friction when the dog moves about.
~ Digestion, stools and urine – normal
~ Tongue colour, nose, ears all normal, no discharges
~ Eyes now OK although a few months back, the rescuer said the vet suspected the dog might have vision problem meaning he couldn't see properly. I tested his sight by moving my hand and fingers a distance from him – he seemed to follow well the direction of my hand.
~ The dog has short brown coat. Skin in general OK except for the extremities. No pain in the joints only the areas covered with sores.
~ The dog only gets to drink and eat in the morning and evening. Nothing in between as the rescuer has to work full time. She can't leave any bowl in the room where the dog is kept whole day as he would knock over anything in his attempt to move about. In this matter, I told her my concern that the dog might be dehydrated during the hot days. But nothing much could be done as there is no one at home to take care of him. He was looked after by a few fosterers before but they were worn out mentally and physically caring for him. Now he is back under the care of the rescuer.
~ The rescuer would take him every weekend for a swim which he seemed to enjoy. He could move in the water easily but not on land.

The vet has suggested that the dog take a daily dose of B-complex. Nothing further he could do.

I have given the rescuer Bio 24 (Calc Phos, Ferrum Phos, Kali Phos, Mag Phos, Nat Phos) to give to the dog and Homeopathic dusting powder (antifungal and antibacterial) for the sores for the time being. Since his paws are sensitive to touch, I have asked her to massage the dog's backbone area gently (head to tail) instead. Hopefully these could help him in some ways to stabilize his condition and not deteriorate further.

Grateful if anyone could help this poor dog with further suggestions on homeopathic remedies or other methods like acupressure. He is only 11 months and has many years ahead of him. The road is going to be tough for the rescuer and the dog but we can only hope his condition would not deteriorate further.

Thanks.
