Why is my male dog so desperate for my female dog in heat?

It's probably because Zeus wants to mate with her that he won't leave her side. Male dogs can sense when a dog is in heat, and they will be attracted to the female and stay by them so they can mate with them every chance they get. If you don't want them to have puppies, I would keep them separated completely until her heat is over, which usually lasts around three weeks. You can get him neutered as well so that puppies will not happen, but he would still have to be kept separate from her for at least three to four weeks post surgery. This is because he would still be able to impregnate her, he will not be sterile fully until after those weeks have passed. I hope this helps!

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.

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.

I can understand being worried about your male dog, but this is normal. He wants to mate with Bailey, and the hormones are effecting him and causing him to pant. This can go on for days, and sometimes males can will stop eating and can injury themselves trying to get to the female so they can mate. If you do not want puppies, the only way to stop this behavior is to move either Bailey or your male dog out of the house. Preferably the male dog so you can keep Bailey isolated to prevent her from mating. Have him go stay at a friend's house while she is in heat (this lasts three to four weeks). I would also make an appointment with the vet to have him neutered, and I would get Bailey spayed after she is out of heat. Otherwise, you will have to deal with this every time she is in heat. Best of luck.

Thank you for submitting your question regarding your dog. This is normal behavior for an intact male dog. If you have him neutered, his hormone levels will decrease. This will resolve this behavior. I hope this information helps!

I see that Lelo isn't spayed, but I'm not sure if Brady is neutered or not. He is likely very interested in her because she is an intact female and he may want to mate with her. I would not recommend mating them because it sounds like Brady's breed mix leads him to be a much larger dog than Lelo, and you should need mate a male to a female that is much smaller than her. This leads to large puppies and subsequent birthing difficulties often leading to emergency c-sections. I recommend having Lelo spayed and Brady neutered if he's still intact. That should help with his obsession with her. I would make an appointment with your vet this week. Good luck, I hope this helps!

This behavior is often considered part of a dominance issue and can be seen amongst any dogs, even neutered dogs occasionally. Be aware that your puppy will be able to mate very shortly and you should consider neutering her or making arrangements to keep them separated for 3weeks when she comes in heat next
