Are Spayed Dogs Still Attractive to Male Dogs?

You may have spent quite a good chunk of money to spay your dog and now that your dog is spayed she's attracting males dogs, what gives? Isn't she supposed to no longer be interesting to male dogs? Well, for a good part yes, but if this attraction started out of the blue, you are right to be puzzled and think that something is amiss. First of all, let's take a look at what causes male dogs to become interesting to females.

An intact female dog is a dog who is capable of reproducing. She is intact by definition because she is still equipped with ovaries, oviducts, uterine horns, and the uterus. A female who is spayed instead has been opened up and has undergone a medical procedure known as an ovariohysterectomy (OHE). This surgery basically removes her from her capacity to reproduce. At the same time, since her reproductive organs are removed, the production of hormones such as as estrogen and progesterone is also halted. These are the hormones responsible for triggering the dog's heat cycle.

Most dogs are generally not particularly interested in females from a sexual standpoint until the female gives signs of going into heat. Blessed with over 220 million olfactory receptors in their noses, a male dog's nose certainly "knows" when a female is in heat. Indeed, a female dog gives off very powerful pheromones which help her advertise her availability. There are countless stories of male dogs capable of detecting the smell of females in heat from a distance. Many of these pheromones are released in the female dog's urine which is why male dogs are so obsessed with smelling areas intact female dogs have urinated on.

So if your dog is spayed, and as such, not capable of going into heat, how can she be attracting males? Great question! There are some explanations for this that we will look at in the next paragraphs.

Why Is Your Spayed Dog Attracting Males?

So things definitively are not adding up..your dog was spayed, her reproductive organs removed and her capability to produce hormones associated with the heat cycle is halted, so yes, how can a spayed female attract males out of the blue? A good assessment would be obtained by analyzing if the female attracts only one specific male or all males in general. Let's look at some possible explanations.

Warning: Dog in Heat

No worries, the dog in heat is not yours. Indeed, if your dog was spayed correctly, she should never go into heat or act as if in heat. In this case, we're talking about some neighbor's dog in heat. Indeed, if you own a spayed female, and now suddenly your male dog is obsessed with her, it could be there's a female dog in heat in heat somewhere in your neighborhood. This is what happened once to a client at the vet's office, her male suddenly was obsessed with her, and after obtaining a clean bill of health, she casually noticed one of her neighbor's dogs was in heat. Unable to gain access to the dog in heat, her male dog redirected his pent-up frustration towards the spayed female dog!

Tissue Remnants Left Behind

If your dog is spayed and is now acting as if in heat and your male dog is sure interested, yes, you are right to be concerned. In some rare cases, a dog's spay may go wrong. In this case, it's likely that during the spay surgery, small parts of ovarian tissue were left behind. Left in the body, this tissue grows and then triggers the brain to produce the hormones associated with the heat cycle, explains veterinarian Janet Tobiassen Crosby. In this case, if the uterus was successfully removed, your dog technically cannot get pregnant, but if in doubt, go on route to your closest vet's office to have your dog checked out!

Undiagnosed Medical Condition

So there are no female dogs in heat that you know, yet, male dogs have shown some definite interest in your dog, what else can be the problem? Consider that in some cases medical conditions may cause your dog to smell a bit like a dog in heat. What medical conditions cause this? In this case, we're probably looking at a possible bladder infection, infection of the cervix, vulva or a case of vaginitis. In some cases, the anal sacs may be also to blame. All these conditions can sometimes make a female dog attractive to males. The reasons though aren't still entirely clear, explains veterinarian Mike Richards.

Animals exhibiting signs and symptoms of distress should be seen by a veterinarian immediately.

Questions & Answers

  • Even though my dog was spayed three years ago, she still releases the hormones meant for her to go into heat. I know this because our male dog humps the life out of her for about a week every six months. What can I do?

    This is interesting. Have you by any chances also noticed any swelling or discharge during these times? Sometimes, when dogs are spayed, it can happen that the vet accidentally leaves some ovarian tissue behind. When this happens, dogs go still in heat when spayed and can even develop pyometra (it's called stump pyometra). I would talk to the vet who spayed her and ask and describe what you're seeing.

  • When I got my dog the person that gave her to me told me that she was spayed, but my male Chihuahua is trying to make with her. What could be the reason?

    There are several possibilities. 1) The person who provided you with this dog gave you wrong information 2) she is spayed but the vet accidentally left some ovarian tissue behind (quite rare), 3) she is spayed but there is another female in heat in your neighborhood and that is exciting him, or 4) she is emanating some smell due to some health issue.

  • My spayed female cat is attracting male cats that have not yet been neutered. They typically do not mount her, but they constantly follow her around everywhere with their noses as close to her bottom as possible. What could be causing this?

    Sometimes a piece of ovarian or uterine tissue is left behind during the spay surgery, and this may cause her to go into heat and attract males. Not saying this is the case, but it may be a possibility.

      It would be interesting to hear back from some people who have found out the issue, but I guess they no longer google it when they no longer have the same issue.

      My two intact male dogs are relentlessly bugging my spayed female and she's getting so fed up she's at the point of viciously attacking them every time they come near. She is smaller than them so is not injuring them so they just ignore the behaviour.

      Great information! My Pit Bull is about 18 years old now and my male dogs have been all over her! It started a few months ago, and although I have 3 other spayed females, the boys seen to only want to bother her! I will take her in for a check to see if she has an infection as she is quite old now.

      Thanks again!

      Has your daughter's dog been checked for any medical condition? I am assuming she is spayed.

      Thank you for this article. My daughters dog 18 month old black lab terrier mix comes to visit now and then. My dog Chico, 14 year old in tact male rat terrier goes absolutely crazy when she comes. She lived here when my daughter got her at 8 weeks old. She has been fixed. He just won't leave her alone! She sspent the night last night. He kept me awake all night wining because he couldn't get to her. Is he too old to get neutered? Thanks!

      At least until the issue that's attracting him in the first place is resolved.

      Will my male dog eventually lose interest in her and stop trying to get at her?

      The article above explains it. Fixed and spayed are the same thing.

      In my case the male lives in my house also and for the last week he chases her constantly so we have to keep them separated most of the time.

      It does happen every now and then, even though not that often. It often leaves owners puzzled and that's understandable! Sometimes though, the mystery is never really solved;)
