I have 2 beautiful puppies, 12 months Labrador, 11months Rottweiler, both males. Got them very small, 9 and 5 weeks old . They grew up together, they eat next to each other without a problem, they play good, rarely get a little ruff but ntn crazy. They spend night together in the backyard, ok size , about 3000 square feet. So far no problems, but i was thinking to neuter the Lab(as i want puppies from the rottweiler later on) in order to avoid future problems and fights when both in heat. Honestly I'm not a big fan of neutering, as it changes the hormonal balance of an otherwise healthy dog, so of possible i would like to avoid it. I'm hearing so many different opinions i don't know what to do. One side telling me I'm crazy and they gonna kill each other, others telling me ntn gonna happen as they grow up together and the rottweiler is so much more dominant that he will be the alpha while the labrador will accept his role as a follower and respect him........ Any inputs? Any experience with 2 non neutered dogs living together?
