New mastiff owner here, I have always wanted one. Grew up with St. Bernard my whole life. My boy is 3 months and 47 pounds he is growing good. Training is going good. I’m a bit worried about a growth he has on his penis. Seriously! I don’t think his bulbus gland should be red and swollen at this age. Any input should be great. I brought him to the vet and the vet gave him antibiotics.
