When I took in my MIL little dog puppy my 1 toy poodle did not like her and the puppy would run into the other toy poodle and knock her over, she just had too much energy for the 15 year olds. They were glad when the puppy went home - it created a lot of stress for me - trying to keep peace. I would not do it again. When these go I will proably get another - only one this time.
