My Baby Ozzy goes to daycare 3 times a week, Mon/Wed/Fri.
He loves it. They seperate the pups/itty bitties from the large dogs but do put the little ones with quiet big dogs when there is one there so they get used to them. They are housebreaking him to go potty outside for me so that is great. (he uses pads at home)
He got all As on his evaluation except for his interaction with big dogs but he is getting better everyday. (he is only 13 weeks old and 2lbs 10oz)
He has 2 girlfriends, a schnoodle and a lhasa. He adores them and tries to boss them around. (my little Napoleon) He has recently discovered the joys of humping so I'm worried he may be starting some trouble at school today

Next week we'll go to our 3rd vet visit and discuss neutering!
I think it is such a great experience for him. He is so well adjusted but I do pay $24 a visit so it's a bit much but I can't stand the thought of leaving him alone everyday while I'm at work so it's worth it.
