I use Isle of Dogs for grooming. I love it.
Also in terms of training, I can't offer potty training advice cause I indoor train with a toilet system, so I know nothing about outdoor stuff.
Make sure because she is so young that you don't expose her to other dogs until she's done all her required shots and the vets say she can go out, (I think it's the second set they're good after).
Also training has to start now if you want to do it "right" :P lol. But there really is no right way, as long as you're a positive trainer and know what your goals for your dog are.
The most important thing to teach your little one is the "drop it" and "ouch" command. Because she came home early, the "ouch" works well to teach bit inhibition. If her teeth come into contact with your skin, say "ouch" in a loud deep voice, then that startles them a little and they release, immediately replace whatever she had in her mouth (hands feet etc) with a toy or treat. So she learns its far more pleasant and fun to chew toys, not you.
Also drop it, teaches them to drop whatever's in their mouth with the pay off of getting something better. This helps when you want to teach fetch later too. It also helps teach "leave it"
To teach drop it, give her a toy, it works good on tugs, then when you want her to drop the toy, push the toy backwards towards her, this gentle motion encourages them to drop the toy, and the second you feel the pup release, praise and give a treat or a better toy. Don't make the same mistake I did, I stopped here, now harley has figured out that drop it only counts when I hold onto the toy, if I say it when I'm not touching it, he smiles and runs away
.
I recommend getting a few good training books. I wasn't a big fan of clicker training when I started, then realized it was a necessity. I don't use a clicker, but I use a marker word. "My Smart Puppy" is a good book.
have fun! she is adorable.
