Puppy Period Panties

If your pup is an unaltered female (meaning that she hasn’t been spayed), you will eventually have to deal with her first heat cycle.

Although the process doesn’t unfold exactly as it does in humans, it’ll essentially be like she’s having her period. Yup, your little girl is all grown up!

This can obviously cause a bit of a mess but thankfully, there are products on the market that can help protect your home and prevent your dog from leaving a dark red trail everywhere she goes.

These products are typically called diapers, but we’ll be calling them period panties, as they’re pretty similar to the human version of these products.

We’ll recommend three of the best options available below, and then we’ll explain a few other things you may find helpful when dealing with your dog’s first period. We’ll even explain a neat DIY solution, in case your dog’s period starts before you receive your period panties in the mail.

Period Panties for Dogs

How Often Do Female Dogs Get Periods?

Most dogs have a six-month-long heat cycle, so they usually get a period twice a year, and it will last for a few weeks each time. However, just like human periods, the timing of a dog’s heat cycle can vary pretty considerably.

Some dogs may experience a heat cycle that lasts only four months or so, while others may only get one period per year. Typically, small breeds experience more rapid heat cycles, while large and giant breeds go longer between each cycle.

The timing of a dog’s first few heat cycles can be erratic, but they’ll usually become more regular with age. However, even the most regular dog in the world can experience an oddly timed heat cycle; this is rarely the type of phenomenon by which you could set your watch.  

When Do Dogs Get Their First Heat Cycle?

Dogs generally reach sexual maturity between 6 and 24 months of age, depending on the breed, health of the dog, and individual biological factors. Usually small and toy breeds enter their first heat cycle earlier than large and giant breeds do, but there are exceptions.

So, if you are looking at your unaltered young puppy, you’ll want to start planning to deal with her first period somewhere around the time she turns 5 months old. She may not have her first period for some time after this, but you don’t want to be caught empty-handed when she starts.

How Can You Tell When Your Dog’s Period Is Imminent?

It is often tricky to determine when a dog’s period is about to start, particularly for young dogs who’ve yet to develop a consistent pattern.

However, there are a few things you can watch for, which may tip you off that your dog’s period is about to happen.

Just be on the lookout for the following signs:

  • Your dog’s vulva may begin to swell at the beginning of her heat cycle. This often occurs at the same time they start menstruating, but it’ll occasionally start before she begins bleeding, so it is worth keeping an eye on her parts.
  • Some dogs become exceptionally clingy right before their heat cycle begins. My own pup does this – whenever I notice her laying on top of me, instead of beside me, for a few days, or following me around with more purpose than usual, I know her heat cycle is probably about to start.
  • Some dogs may exhibit changes in appetite before they start their period. This can obviously occur for a variety of different reasons, but it’s a good idea to monitor your dog’s appetite in the weeks leading up to her heat cycle.
  • Many dogs pant and lick their lips frequently as their heat cycle approaches. These types of behaviors can occur for other reasons too (they’re often displayed as calming signals), but, if they don’t appear to be associated with illness or injury, they may indicate her period is approaching.
  • Some dogs begin exhibiting general behavioral changes in the days or weeks leading up to their heat cycle. This is admittedly an extraordinarily vague kind of thing to look for, but some dogs will act a bit strange before their period starts. Some may become a bit more territorial or exhibit more resource guarding, while others may stop being as obedient as they usually are.

Finally, it is important to note that the color and consistency of the discharge produced during a dog’s heat cycle changes over time. For some dogs, the discharge can be remarkably clear at first, before changing into the typical red and opaque discharge most people expect.

So, if you notice any type of discharge it should signal you to monitor the situation carefully and make sure you have period panties standing by.

An Emergency Canine Period Panty DIY Solution

You’ll definitely want to acquire a set of period panties for your dog’s first heat cycle – there’s simply no other way to contain the mess that’s easy and effective. However, owners may be caught off guard by their dog’s first heat, which can lead to quite a predicament.

Fortunately, there are some DIY dog diaper solutions that can help a bit while you wait for your dog’s period panties to arrive. It isn’t an ideal solution, but it can be quite helpful for a day or two.

Here’s a quick and easy solution you can whip up ASAP:

 First, gather the necessary materials: one pair of men’s underpants (“tighty whities”) and a pad. You may also need a few 10- to 12-inch-long zip ties.  

 Next, stick the pad to the inside of the underpants. You’ll want to place it in the crotch area, but it may take a bit of trial and error to get the right placement.

Then, have your dog step into the underwear, but be sure that the underwear are on backwards. This way, you can thread your dog’s tail through the fly.

Wiggle the underpants around a bit to make sure that they’re fitting properly, and that the pad is appropriately located.

Lastly, if necessary, use the zip ties to keep the underwear snug and in place. You may need to experiment a bit to figure out the best place to use the zip ties, but one good method is to thread a zip tie through one of the legs, across your dog’s butt and out the other leg. Then connect and tighten down the zip tie (be sure to trim any excess).

Again, this will not be 100% effective, and it will surely become a pain to put this on and take it off several times a day. But, it will help contain most of the mess, and it will help you get through a day or two until you can get your hands on a real pair of period panties.   

You may also want to consider getting some extra dog car seat covers and couch covers when you know your dog’s period is approaching – this way you can mitigate and potential damage to your furniture and vehicle!
