Got our beloved pooch number 2 at 10 weeks. She was an unwanted farm puppy, jrt cross something. She's been great, but now at 8 months she is a flipping horror. She takes every opportunity to leap on our 6 yo rescue dogs back. He is amazingly tolerant as he has always been reactive towards adolescent males, which is why I got a female puppy. She cruises on walks looking for other eager pups for play, barks randomly and rips things to shreds. I know its a phase, but just wondered if anyone any tips to get through this testing time!!!?
