Your dog will only be on Earth for a fraction of the time you’ll be here, so it’s important to take advantage of every moment of sunshine you have together. Whether you’re vegging on the patio chair or hiking somewhere new, having your pooch by your side makes summertime so much more magical.

But there are a few details about the warmer months that aren’t so nice, especially the bugs. Mosquitos are particularly annoying on those perfect summertime evenings, but do they bug your dog as much as they bug you? Do mosquitoes bite dogs? Are mosquitos dangerous to dogs? There are so many questions to ask!

If you spot your furry friend scratching while you’re deep in the woods, they just may be itching a mosquito bite. Although a fur coat may seem like it would protect against pesky mosquitos, the determined insects have a way of finding spots with the thinnest areas of fur. They may even nip at your dog’s nose or paws — anywhere where there’s no hair (try saying that five times fast).

A canine mosquito bite could look exactly like a mosquito bite on a human: a small pink welt that comes with a lot of itchiness and discomfort. Some bites will naturally swell more than others, but the bite itself is rarely concerning. If your dog repeatedly scratches or licks the bite, however, they could be at risk of causing a hot spot or even an infection in the small wound. Once you’re aware of a mosquito bite on your dog, it’s a smart idea to check on it once or twice a day until it heals.

Although the vast majority of mosquito bites are merely annoying, there are rare cases when a dog can become ill after being bitten. The biggest risk is heartworm, which is transmitted primarily through bites from infected mosquitos. Heartworm can be fatal if left untreated, but the good news is that it’s both treatable and preventable. This is why it’s essential to start your dog on heartworm prevention before spending time outdoors this summer.

Other mosquito-borne illnesses, such as West Nile virus, can also infect dogs. This disease is often severe and requires medical intervention, so don’t hesitate to visit the vet if your dog acts unusual following a trip outdoors.

In extremely rare cases, dogs have experienced allergic reactions, including anaphylaxis, in response to mosquito bites. This medical emergency requires immediate veterinary attention, but unfortunately, it can be difficult to predict.

Step one when protecting your dog against mosquitos is actually protecting against heartworm. This is the most serious complication of mosquito bites, so prevention should be a priority. Additionally, you can try a number of natural mosquito repellants in your yard or even attach them to your dog’s leash — just not on your dog, please! Citronella, rosemary, and lemon essential oil are great options, but they can be dangerous if your dog gets into them.

The best thing you can do is eliminate any mosquito breeding grounds, like standing water, or keep your pet indoors when mosquitos are most active. You’ll be saving yourself the annoyance of bug bites, too!

Now that you’re more prepared to face mosquitos this summer, you can ensure that your furry friend stays safe and itch-free no matter where you’re headed. Happy tails!

When you look into the eyes of your best furry friend, obediently waiting for their treat, it can shock you to remember that these beasties came from wild wolves. Once you start to dive into the history of canines, you uncover a fascinating series of events, complete with twists and turns.

Over the course of thousands of years, we've domesticated these animals (or possibly they domesticated themselves) until they turned into the pup pups who live alongside of us now. But the question remains, "Did dogs evolve from wolves?" We'll walk you through their evolution and what it means for your pet today.

Are dogs lactose intolerant? Here’s the science behind it
Wait — is my dog lactose intolerant? There's a good chance the answer is yes

You've likely heard of lactose intolerance in humans. Perhaps you don't have this issue and are a self-proclaimed cheesemonger. Your answer to "Got milk?" has long been yes. While fixing a cheese board or pouring milk into a bowl of cereal, you may notice your dog staring at you with the biggest brown eyes. Maybe they want a treat just for them or some pets, or perhaps they want milk. Isn't milk a cat thing?

No. Cats can become lactose intolerant after weaning. Are dogs lactose intolerant? The short answer is that dogs are often lactose intolerant, but the science is more nuanced. As a general practice, you'll want to know about safe and unsafe human foods to feed dogs so you can avoid giving toxic foods and seek prompt care if your pet eats something they shouldn't. Here's the 4-1-1 on lactose intolerance in dogs, including the science, symptoms, and management advice.

Do dogs have belly buttons? The answer may surprise you
Your dog's belly button will be hard to spot, but we promise that it's there

You may find yourself rubbing your dog's tummy one day and wondering, "Do dogs have belly buttons?" It's true that you won't see anything like our navel on your pup, but that doesn't mean the belly button isn't there. In fact, all placental mammals have belly buttons (meaning you won't find them on a kangaroo or a platypus), and that includes our puppers. While in day-to-day life you don't need to think much about your dog's belly button, you should have some idea of where it is and what it's supposed to look like in case something ever goes wrong down the line.
What does a dog's belly button look like?

When a wolf gives birth to a litter of puppies in the wild, she chews the cords off shortly after delivery. Usually when our pets have babies, a vet or experienced breeder will cut them and give the newborns a quick check-up before returning to mom to nurse (of course, some dogs take care of this themselves, too). A few days later, the remainder will just shrivel up and fall off on its own. Behind this, they'll have a permanent flat scar, which generally causes no harm or discomfort (we'll cover later when it's an issue).
