Hi i'm hoping someone can help me or give me some advise regarding our puppy bullmastiff. We got murphy when he was 7 weeks old he is now 8 weeks. Over the last few days his front legs have started bowing over very badly and he was walking on the outside of his paws. Murphy was the runt of the litter and i was told he was the first to run and walk about. The breeder fed him on a cheap tesco's puppy food, i have recently weaned him onto wainwrights puppy food for large breeds. I took him to the vets last thrusday and was told that it could be the ligaments not growing as fast as his bones and that he should grow out of it, but he is getting worse so taking him back tomorrow. Has anyone ever had this happen?
