If he is pottying in the house I definitely would limit his freedom! Even though he's older and mostly trained he's in a new environment. Using a crate will teach him how to hold it while inside the house. Sometimes dogs need a refresher course of sorts. Make sure you are cleaning the spots up with an enzymatic cleaner to actually break down the smell so he doesn't think he's allowed to pee there like he would outside. If you don't have a "go potty" command I would start using one so he knows what is expected of him as soon as he goes outside once he goes then he can play or do whatever. Also, make sure you are keeping his feeding and potty times on a very strict schedule while doing all this. It helps you better estimate when he needs to go. I hope that helps!

Thanks everyone for the help! I agree with everyone about discounting as well. I try to confirm a pricing once I've met the dog and discussed how much involvement each dog will require.

I've had some people not book with me because they expected me to discount the other dogs of they owned multiple. It's not been every multiple dog situation but I'm still curious
