The usually mostly reliable internet is giving me conflicting advice on grooming for my new Great Pyr. Some places say brush daily, others say brushing daily can cause broken hair and frizziness, so only brush weekly. So places say bathe weekly, others say wet baths can cause matting, and should only be done when they're really dirty. And I have no idea if he's going to need cut or not, or if there's any other grooming that needs done. (I'll be taking him somewhere for his nails, since he has the double dew-claws in the back, and I've never been good at doing nails, lol). Also, he's about 1 year old (I think) and I'm pretty sure he's a pure-bred, but he doesn't have that big main around his neck. Will this grow in as he ages, and when should he be done growing? Is he full grown at 1 year, or is he going to get bigger? Here's some pictures of him. I hope they're not huge, I'm not sure how to resize?
