Hi all, I am a first time berner parent. My male berner puppy Rusty is almost 6 months. He was extremely playful and lively when we first got him but in the last two weeks he has developed a limp and is trying to keep weight off his hind legs. He moves very slowly and prefers laying down. Our vet has performed X-rays and has leared him for any signs of dysplasia but has instead attributed this to growing pains. However, we are bringing him in for a second opinion. Has anyone experienced this with their berners? He als seems to be on the small side (52 at 5 weeks). Any thoughts are welcome!!
