I don't know who is doing the current research on the behavior of unneutered dogs but it is my experience of a number of decades that unneutered dogs have issues. They tend to be territorial and restless. They do on many occasions mark. It is their natural instinct as a whole male dog to be territorial and to mark every where they go. Some, not all, can become aggressive and protective of their area. It can become an issue for a family that wants a calm friendly pet. If there is a female that has not been spayed anywhere within several miles the male will smell it and be effected by that odor. I don't think it takes a research scientist to realize what a whole male is going to want to do when it smells a female in season. Be a good neighbor and spay and neuter your pets.
I have seen way too many trends in scientific research change from decade to decade. What was good by one set of standards changes with the next group of people who get together to crunch their numbers. Use some common sense and do what is best for your family and your pets. |
