My miss Watson is about 8 months old, she is a great dog, polite, well behaved, very well potty trained...... She is fine on her leash as long as she is taken down the porch stairs in the back of the house, and to the left of the stairs she goes potty, then she wants to go right inside, if you don't take her right in she will sit at the door and wait for you. I try to walk both of my pups once daily, but Watson goes psychotic on walks. We have a corner property she gets about 10 feet from the house and starts going crazy, darting back and forth and then spinning around you, then she starts jumping at you trying to bite you, she gets quite vicious, get to her to the porch and she turns into the perfect pup again... Tried pinch collars, harnesses, muzzles (she lays and refuses to budge), food etc. NOTHING helps. It's just getting worse, the trainers and vet said to put her down... Not an option. She can't walk with Sherlock because she will wound him.
