Blue dogs are prone to skin problems. At least I see a lot of post about this around PBC. Skin problems ... always seems to be a blue dog ... sometimes a white dog. Don't shop for color. For a dog that's going to be with you for the next 12-20 (optimistic LOL) years, color should be the last thing to worry about. I would want to know the sire and dams temperament if buying a pup and interact for a period of time with a dog I think I like, if acquiring a young dog. Color be damned LOL. The first thing you should do when getting a pup is take it to a vet. The vet will outline a course of puppy shots. Expect to take the pup back to the vet for shots every 3-4 weeks until the pup is 14-16 weeks old and the puppy shot series is complete. ALSO, discuss heartworm prevention and parasite protection/prevention. I use Trifexis but other medications may be more appropriate depending on geographical location and types of parasites common to the area. As far as training, if the pup will be a house dog and live inside most of the time, it would behoove you to start research NOW on how to house break a puppy. There are MANY ideas about this and whichever method you choose, remember that patience, persistence and consistency is the only way to go. Regardless of the training method used, THERE WILL BE ACCIDENTS. So, DO NOT hit (even with a newspaper), kick, strike, yell at or curse your pup. The fault is with YOU and not the pup ... adjust your methods accordingly. It may mean taking the pup out more often. A general rule of thumb is that a pup can "hold it" for 1 hour ... for each month of age the pup is, PLUS 1 hour, EXAMPLE: An 8 week (2 month) old pup can reasonably be expected to hold it for 3 hours. When house training my pups, I set my alarm clock when I go to bed, to go off after 3 hours. When the alarm goes off, I pick the pup up and take it to an area previously used outside. The pup generally "goes" right away. I HIGHLY praise the pup, pick it up and return inside to await the alarm in another 3 hours LOL. Welcome !!! And whatever your choice for new best friend ... Good Luck !!!
