my dog is one year old. she was happily doing her business outside. I reluctantly fostered a puppy for a few weeks and my dog didn't like it picking up her toys, eating and drinking from her bowls although I tried to stop that. a few days ago, my dog pee'd on the floor 3 times in one day while looking at me very dejectedly. I may have imagined the look but I sent the puppy back . I made a big fuss of my dog, being extra kind to her, but now 2 days later she pee'd on the floor twice. ive taken her out and rewarded her for peeing outside. just ruffling her ears and saying good girl .will this work? is there anything else I can do please?
