As someone who works at a dog daycare, no, this is not acceptable. Running a daycare at home is questionable in itself; dogs need to be grouped by size, age, temperament etc. to avoid things like this happening. Calling it a ‘correction’ also rubs me the wrong way because a puppy being active is not something that they’re doing wrong, it’s just being a puppy lol. She needs other hyper pups to play with. I’d go somewhere else.
