My soon-to-be-coming home puppy will be coming home soon. I've done some reading online and assume that Jerry's coloration is black/white/brindle. Do noses like his continue to pigment in further? Lastly, any good well-rounded food recommendations or stick with what the breeder currently is feeding him?
Welcome! Adorable pup. Dark pigmentation deposition will continue until the nose is fully black (in most cases). There are a lot of threads dedicated to food here, and because no two BT's have the same digestive system, brands that work for one dog may not agree with another. It is a good idea to slowly introduce a new type of food to your pup. Over a few days, you can introduce a meal with 75% old food / 25% new food. Then, increase the new food to 50% for a few days (then 75% and finally 100%). My BT had a very sensitive digestive system over her first year of life, and it took a while to find a high-quality diet that agreed with her. We now use Orijen kibble, which our dog loves and can digest very efficiently. Here is a nice site for reviewing dog food brands, etc.
