Hello. Congrats on being able to get a dog soon. I have a few thoughts that I hope will help.
There are some websites out there that can help you find a breed that fits with your lifestyle/living situation. This is one -

I have had only rescued dogs from the street, so I don't have experience with dog breeders. Most were mixed breeds although one was likely 100% poodle and another was very cocker spaniel. One thing to consider is that purebreds often have breed-related health issues. Mixed breeds have less of a problem there. If you decide on a purebred, definitely investigate the breeder. Reputable ones should do health testing, to reduce the incidence of these health problems:

I hope it works out for you!
