Why is my male dog obsessed with our new unspayed female dog?

Since he is unneutered he may be picking up on her scent even if she is spayed, it's also a way to show dominance over other dogs. If you don't plan to breed him I suggest getting him neutered. This will help the behavior lessen over time and will also prevent some potential health problems as well as reduce the urge to roam and possibly get injured if he escapes looking for a female in heat. You can try getting him obedience training so he will be better behaved and more likely to listen when you try to separate them.

Hello. He is just being a male dog. Even after neutering, some males may still try to mount females, but in his case, he is still strongly attracted to your spayed female. If you do not plan on neutering the male, keep an eye on the male as the female can get annoyed at him & you may have a fight on your hands. If your male is still quite young, he may mature out of this behavior as his instincts are very strong right now. Just keep an eye on him.

if Prince is not neutered, this may be the reason behind the behavior. Neutering Prince will help but the behavior will not change over night. Here is a link about introducing dogs: https://www.petcoach.co/article/5-tips-to-introduce-a-puppy-or-dog-to-your-older-dog/ Make sure to monitor all interactions to prevent injury. Keeping Prince on a leash will help you to provide better control. Making sure both pets are well exercised prior to the meeting can help as well. Do not leave the pets together unsupervised. Best of luck.

IF you are not going to breed them, then getting each fixed is the healthiest option for them. The female is old enough and she has already been through a heat cycle, so she can be scheduled at any time. This can prevent future cancers and the risk of infected uterus. By fixing just her, then she will no longer go into heat and he will not be bothered by her anymore. If you do not have plans to breed him, then he should be neutered also. this can prevent cancer and prostate problems in the future.

Then it sounds like he is just made that way. He may be using this behavior to display dominance. Tell him no firmly and redirect his attention to another fun activity or play thing. It is between you and your vet whether surgery is in Dahlia's best interest or not. In my opinion, it is worth considering now since a heart murmur does not mean she can't develop pyometra. The cure for pyometra is to be spayed, but when they are critically ill with a pyometra, they are at an increased risk of surgical or anesthetic complications. These risks would be amplified in a dog with a heart murmur. Your vet may refer Dahlia to a specialist who can provide more comprehensive monitoring during surgery. Unless my patients are in congestive heart failure, I do not hesitate to spay them with a heart murmur. My own dog has a congenital heart murmur and has undergone several anesthetic procedures during her life without complication. But like I said, your vet knows Dahlia much better than I do!

Actually I doubt there is anything wrong with your dog. Your other dog must be a female in heat and Rambo and her were mating. Females in heat will smell very attractive through sexual hormones and will entice a male dog to mate with her. If you do not intend to breed your dogs, then I suggest you have both male and female desexed which will alleviate the problem.

This is pretty normal. Protecting her from other possible males - doesn't matter if they are human. Doesn't even matter if they are male or female. This could get ugly fast and can turn to severe aggression. If you are not planning on breeding them I suggest you get them spayed/neutered as to not promote any behavioral issues.
