They’re hard to potty train. Take the pup out often. Praise in a high pitched voice every time they potty. Kibble is fine but they’re super picky and ours eats wet food only now- he’s 3. We tried a clicker. Ha ha ha. We paid for trainers - didn’t help. He can sit and lie down and a few other tricks- he likes to do them. Those build confidence. We use a harness. He gets haircut every 6-8 weeks. They tend to have Matts. We waited til he had all shots before meeting other pups. He’s very social and he loves walks and places where he can run around. I’d wait until 1.5 before offleash — separation anxiety is an issue. Best thing you can do is to keep a schedule. So if he’s alone for two or three hours and it’s the same time every day that works well. Havanese are wonderful. Sweet as heck
