Not sure if I can come up with three.. but here goes
Teeth: the vet where I volunteer said Yorkies get the worst tartar on their teeth. Be sure to brush your Yorkies teeth at least several times a week (preferably everyday), and use chews. I just got bully sticks and I really feel just one made his teeth a lot whiter. He chewed on it for like an hour. I've also been using CET Vanilla-Mint toothpaste (smells soooo good
) and CET Hextra chews, so I am not sure which is making his teeth white but it seems to be working. I think I'd suggest bully sticks over CET chews as they seem less dangerous. You have to watch them with the chews though.
Exercise: every dog needs exercise! Even the little ones. There are some exceptions of course but if your dog is crazy hyper, try taking him on an hour or two of exercise daily. That's what happened to Scruffs, and in about a month he finally calmed down. Better behaved too. Then again, he had never been walked before I got him.
House training: I admit Scruffs is still not 100% house trained, but he has never had an accident in his crate and I recommend crates so much!! Scruff is the same way about pooping once in a while in my living room. Sometimes I feel like he just can't hold it... when he is running on the treadmill sometimes he tries to hold it in, but he just goes. I get lazy sometimes
, and he needs like 45 mins minimum of exercise, so I turn on the treadmill, but he takes water breaks and is supervised and enjoys it! Well I'm off topic now, but I suggest crates as it is a big help from him staying out of trouble.
