Do Small Dogs Pee More Often?

OK, here’s one all dog parents will know. Even if you have a puppy, and you’ve been their parent for just a few days, you’ve probably already seen them scent mark. This is when your dog releases a small amount of urine, usually in multiple locations. Marking is a common dog behavior, but if your pup does it often, you might be wondering if that’s normal.

Turns out, lots of dogs do it frequently, but small dogs are most likely to pee often and to scent mark a lot, too. Here’s everything you need to know about the urinary habits of small dogs. 

What is Scent Marking?

Scent marking is a common form of communication across a wide range of animals. Although dogs can scent mark in various ways, they most often use urine, which is obvious to anyone who has watched dogs pee here, there, and effing everywhere while out on a walk.

Urination, and other forms of scent marking, allow animals to convey a large amount of information in an indirect manner. In other words, when they mark, they can communicate without direct interactions, which is a good thing because it helps them avoid stress, the energetic costs of interacting, and potential injury. In many species, body size is closely correlated with competitive ability, which is why scent marking may be especially important to smaller animals, who may be unlikely to fare well in direct encounters.

Do Small Dogs Pee More Frequently?

Dogs have an enormous size range for a single species, but only in the past several years has the effect of size on frequency of scent marking been investigated. Researchers wondered whether smaller dogs take advantage of the indirect nature of scent marking through urine to be more competitive with larger dogs. 

Research on shelter dogs found that smaller dogs pee more often than larger dogs do, and males pee more often than females. Additionally, smaller dogs, males, and dogs who have been at the shelter longer all directed their urine at targets more often, meaning they were scent marking rather than just peeing because they had to go.

What factors contribute to small dogs peeing more often?

The authors of a 2016 study concluded that smaller dogs use scent marking in the form of urination more frequently than larger dogs. Yes, small dogs pee more often, as most anyone who has lived with both small and large dogs is likely to have noticed, and there are multiple reasons for that.

1. It’s natural to assume that the small-dog bladder situation at least partially explains why little dogs pee more often, and that assumption is correct. Small dogs can’t store as much urine, so they need to relieve themselves more frequently.

2. Small dogs have a higher metabolism, so they produce more waste from their energetic ways relative to body size. 

3. Small dogs mark more often, so they are using their urine as a communication method more often than large dogs do.

4. If the smaller dog is little because they are not yet full grown, their age is another factor. Young dogs usually have to pee more frequently than adult dogs.

Can I help manage my small dog’s urination schedule?

Some dogs, especially small ones, just can’t hold their pee for as long as we’d like. It can be inconvenient, but remember that your dog can’t help it — when you’ve got to go, you’ve got to go. Every dog has an upper limit of how long they can go from one pee to the next, and it’s reasonable to guess they feel pretty uncomfortable if they are always pushed to the edge of that limit.

It’s much kinder to allow them the opportunity to pee more frequently than they absolutely need to. To manage their urination schedule, keep a regular routine of trips outside to pee, and gradually increase the time between outings, but never make it so long your dog can’t hold it or acts desperate to pee.

How many times a day should a dog pee?

There is a lot of variation in how often dogs need to go, just like with people, as anyone who has ever gone on a road trip with a group of friends knows. At the absolute minimum, a dog needs to pee three to four times a day, but many dogs need to go far more frequently. A typical dog needs to go five or six times each day, but up to eight  times is far from unusual, and many dogs benefit from an extra chance to go after each meal.

How long can small dogs hold their pee?

As puppies, a general rule is that, at best, they can hold it for no more than their age in months plus one hour, so a four-month old puppy may be able to make it for five hours. That’s only true if they don’t drink a whole bunch of water right at the start of that time period, and they are not playing hard, eating, or chewing on something, all of which can make them more likely to need to go potty. So, this rule means that a tired puppy at rest can make it that long.

Generally, dogs can hold their pee for six to eight hours once adults, but most will naturally pee every four to six hours throughout the day. Most adult dogs can make it eight or nine hours at night without having to go out to relieve themselves, but not all dogs can go that long during the day when they are awake and more active. Senior dogs usually need to go more frequently as they push further and further into their golden years.

Can certain diets or medications help with frequent urination in small dogs?

Medications and diets are factors that can influence the frequency of urination of dogs of any size. In fact, some medications increase the frequency of urination. Any concerns about diet and medication related to your specific dog’s urination frequency should be discussed with your veterinarian.

Frequency of urination is highly individual, so it’s different for each dog. But small dogs (and puppies and senior dogs, too) generally pee more frequently than larger dogs. Their small dog bladders are one reason for this, but a higher metabolism and their tendency to mark more frequently than big dogs are factors, too. Because having a small dog means they need to go out more often, it seems that being a parent to one is the perfect excuse to leave work as soon as possible to get home to them. As if you needed a reason!
