Hola buena, welcome to yt, you already had some good advice here, I will be careful to take him outside since he has not all his vacc yet, also flea and tick season too, (well here on Cali); also have you take him to the vet yet? just to make sure he is ok, does the breeder give you some kind of health warranty? some give you, one or even two years, anyway, take it easy on the sugar, nutrical or nutristart, is best for him just a little and only if necessary, you can get it on Petco or Petsmart.When you have time will like to see some pictures, congratulations!!!
