i have just had a brindle bull cross 58,38 given of a friend he recently got the dog,i have wormed it and tried putting weight on it but since walking it as it was timid ive noticed it walks funny i spoke to a friend who knows the dogs breeding and the history of it and they say no matter how much weight i get on it ,it will never run properly .aparently it had an abcess on its back thats why it walks funny,what do you think i should do as its only a young dog and apparently done nothing ,do you think il be wasting my time ,
