Hello, and welcome to Yorkie Talk.
I think you can change your pup's name to Nemo without a problem. Just keep calling him Nemo during cuddle and play time. Give him treats when he responds to Nemo. I think Nemo would be an easy name for hime to get used to.
1. If you are uncomfortable walking your pup, you should definitely paper train. You can use wee wee pads, or puppy litter with a puppy litter box. They sell different size puppy litter boxes at petstores. I think they even sell large patches of grass to use inside the house for the pups to go in. Anyhow, since Yorkies are small they do fine with inside training. However, you should still take your pup to a park for exercise. Even though your pup is small, he still needs to run around and play especially when he is still young.
2. I think crate training is a great idea, both for potty training in general and for your pup to be comfortable later on. There are a lot of online resources on how to crate train. I am sure you can find out a lot of previous posts about it on this website if you use the search section.
3. Your dog is not going to like being in the crate at first, so keep the crate near your bed. Mia doesn't mind being crated if she can see me. So, I've started to keep her crate on the night stand at night, thanks to YT'ers' suggestions. One person should do the training. But, that doesn't mean that other family members are not going to use the same commands. You, as the primary care-giver, should teach though. It also ensures a special bond between you two.
4. I would suggest feeding Canidae, Merrick's, or Chicken Soup for Puppy Lover's soul. What food to feed is a common topic here, and everyone has their own preferences. I would suggest dry food mostly because Yorkies tend to have dental problems later on. If you can, try to brush your pup's teeth, or consider teeth cleaning at the vet's.
5. Every Yorkie is different, so it's kind of hard to tell which toy your Yorkie would like. Mia has 3 boxes of toys. Here is the tip though. Have several different kinds, and do not leave them lying around. Yorkies lose interest in toys very quickly. When your pup is done playing, put the toy away. Also, I give Mia a toy only after she sits, for example. That establishes that you are the boss. Keep rotating the toys he plays with.
There are many good books out there. I have recently read Deborah Wood's "Little Dogs: Training your pint-sized companion." I think it was a good book, and I would recommend it.
I would suggest that you start training right away, especially if you had behavior problems with other dogs in the past. Also, post some pictures of your pup!!! We all love pictures here. Always feel free to post more questions!!!! That's why we all log on here; to share our troubles and happinesses, and to try to help each other out based on our own experiences.
I wish you the best of luck with your little pup.
