As far as the vet visit, he/she will need a wellness visit only unless I tell you otherwise, I recommend minimal vaccinations and no heart worm, no Bordatella, no flea collars or topical treatments, no lepto. Those are all deadly to them. Spay at 8 months to a year, neuter at around 6 months to avoid marking and if you can hold off on rabies that would be fantastic. If your vet requires it I would ask to wait until one year and give 1/2 dose. If you have a holistic vet available they will usually be more than happy to do this. Once she has her first 3 puppy vaccinations that is all she will ever need. If your vet is concerned about not giving these things they can run a titter and a yearly heart worm test.
If you want to get treats to keep the teeth clean you can get bully sticks, raw chicken feet, chicken necks and treats can be hearts, livers, gizzards, you can dice them up and freeze. Also fresh raw goat milk is a wonderful addition to add daily for a natural probiotic and they love it. Some fresh fruits and vegetables in very small amounts are ok if you would like just make sure they are ok for dogs, there are some are deadly to them. Pure pumpkin or sweet potatoes can be given for an upset tummy.
