Why Is Summer Dangerous For Dogs?

Some Food For Thought For Dog Parents

We all know not to leave a dog in a parked car on a warm day, but summertime presents a number of other hazards to pets that we may not even think of. I’d like to offer a summer picnic of “food for thought.” A collection of things that some dog parents might overlook or that perhaps hadn’t occurred to them, or that new dog owners aren’t yet aware of.


Speaking of dogs in parked cars, that it’s dangerous should go without saying, yet how many of us see dogs left unattended in cars with the windows cranked a bit, and how many of us hang around until the owner comes out? Many things can turn a quick “run in to get a loaf of bread” moment into an eternity, all while your dog sits, perhaps in peril, in the hot car.

How many of us have been behind someone at the checkout, on their cell phone, and rummaging for credit cards and coupons. These can be life-threatening delays to that dog in the car with the windows cranked a bit. The passenger cabin of the car heats up rapidly.


The ASPCA Suggests These Actions When You Find A Dog Locked In A Hot Car

  • Immediately call animal control or 911 if you see an animal trapped in a hot car. Local law officials have the ability to enter the vehicle and rescue the pet.
  • Do not leave until help has arrived.
  • Notify the managers of nearby businesses so they can make an urgent announcement.

Nothing looks happier than a dog with his head hanging out the window of a moving car, tongue lolling at full extension. There is a danger there, too. Dust and debris, moving at high velocity because of the forward motion of the car, can cause penetration injuries to the eyes, nose, tongue and mouth.

There's also the danger of him looking into the sun for several minutes without eye protection. A good pet supply store will have protective eyewear for dogs, and perhaps so will your veterinarian's office and your groomer. It's a good investment for owners of dogs who ride with their head out the window.


Summer is when dogs are exposed to more plant matter, some of which can cause health issues, ranging from gastric episodes to death, if ingested. When you improve the appearance of your yard with new plants, trees and shrubs, it’s a good idea to save the tags that come with them. They contain the taxonomic, or scientific, name of the plant and enable the veterinarian or poison control center personnel to immediately and accurately identify the plant. It's of little help when all you can tell them is that your dog at from a plant with blue flowers and funny shaped leaves.

That saves valuable time in treating a dog that has ingested the plant and, in some cases, seconds count. Also, treatment protocols vary depending upon the plant matter involved. If the veterinarian has to rummage through botany literature to find the exact name of the plant, treatment is delayed.

Summer also means more biting and stinging insects and parasites, not to mention the chemicals we use to combat them. Flea and tick control products for use on the animal are safe*, of course, but the stuff we use on the grass and shrubs can be problematic should pets get into it.

It’s been my experience that consumers (i.e. guys!) routinely misuse lawn and garden chemicals. “I’ll just put it down a little heavier to make sure they’re dead.” Must be a guy thing. Manufacturers spend hundreds of thousands, if not millions, of dollars in research, testing and documentation to prove to the U.S. Environmental Protection Agency (not simply convince them) that when used according to instructions the product will do what it claims it will do. The EPA registration number on the package shows that they’ve done that.

It’s unnecessary to over-apply insecticides or herbicides. I call it the “If you put a bullet between my eyes, I’m dead; if you put two bullets between my eyes, I’m no deader” principle. In addition, you run the risk that the product will not be able to break down properly and do its job.

Conversely, if you try to spread that 5,000 square foot bag of insecticide over your 7,000 square foot yard, it obviously won’t work. Rather than kill the bugs, their surviving that dose could enable them to build up an immunity to the product's active ingredient.

And if you have a dog or cat, don’t use cocoa mulch (made from the shells of cocoa beans) in your mulch beds. It can contain dangerous levels of chocolate’s toxic agent, theobromine, a cardiac stimulant that can kill dogs and cats.


If your dog is a swimmer, pay close attention to his ears, especially if he has floppy ears, to avoid infections. Your veterinarian or pet supply store has products that will help dry up water that collects in the inner ear.

When you go for walks, try for around sunup and sundown, so the pavement won’t be so hot, and bring along some water for the both of you. When walking off- pavement, be aware of ticks, which hang out at the ends of brush and grasses. Make sure your dog is protected with appropriate tick control products, and be sure you're protected too. Wearing long sleeves and pants, with the cuffs tucked into your socks, provides added protection

Dogs are also subject to sunburn on their noses and, in the case of short haired dogs, the rest of the body, so keep that in mind when outside. Should you have your groomer shave the dog down for the summer? That’s controversial. One school of thought says, “Obviously, if you shave him down he’ll be cooler, so it’s a no brainer.”

The other school of thought says, “Dogs need their coats to thermoregulate and to protect them from biting/stinging insects, thorny brush, and the sun.” Most veterinarians will advise against it, but they generally don't go on a crusade against it. You make the call.

Wild animal encounters are more likely during the summer months, and not just in the woods. Woodland creatures are common in suburban, and even urban, backyards nowadays. Make sure your dog’s and cat’s rabies shots are current and, if there is an encounter with a wild animal, examine your pet for puncture and scratch wounds and other injuries. If your examination is positive for any of the above, don’t mess around with it; call your vet. And you might want to keep your eyes peeled for parasites, too.

Cookouts can be dangerous because well meaning guests are likely to share their food with your dog, in which case the dog’s stomach might have something to say about it. You don’t want Boomer ralphing all over Aunt Agnes who came all the way from out of state plus, hours later, Boomer’s intestines might have something to say all over your living room carpet. Additionally, some people food is harmful to dogs.


Some people, especially those who are not particularly fond of animals, find it entertaining when your dog becomes a canine garbage disposal. It’s not fair to the dog to put him through all of that. And guests could carelessly leave alcoholic beverages unattended while they go up for another helping of your famous Death By Chocolate dessert, creating an opportunity for your dog to drain their glasses and suffer alcohol toxicosis, which can be fatal.

A drunken dog is a dog in serious trouble. Signs of alcohol toxicity include vomiting, loss of coordination, disorientation and stupor; in severe cases, coma, seizures and death. It takes a while for the alcohol to be absorbed into your dog’s bloodstream so symptoms may not appear for 3 or 4 hours after ingestion.

Keep in mind that the noise and activity of your party can be confusing and frightening to dogs. They are, after all, pretty much creatures of habit and anything that disrupts their routines can be stressful, and there’s no telling how they’ll react. It’s even scarier when they’re not familiar with some of the guests. Certain dogs react, either positively or negatively, to certain types of people, i.e. men with beards, men who wear hats, women who are animated or loud, or heavily perfumed. Results could be negative for everyone.

And, of course, there's always that threat of the dog, attracted by irresistible aromas, jumping up on the grill, getting seriously burned. Another danger is that he could send the grill flying, which could cause further injuries or fires if patio furniture, outbuildings, or guests clothing ignite.

Most experts agree that if you’re going to have an event with lots of guests, keep your dog or cat isolated from the activity or make other arrangements for their care on that day.

Be very, very certain that a flea and tick spot-on product labeled for dogs, isn’t applied to cats. The concentration of active ingredient appropriate for dogs is toxic to cats. Don’t even let your cat groom your dog while residual spot-on material is evident on your dog.

      Hi Pat, great to have you stop by! As a matter of fact I was working at a store today where a customer complained to a cashier that there was a dog in the car unattended. The driver went out there a minute or so later, so was only in for a quick errand...but you never know what kind of delays might happen, long lines, computer glitches, price checks, etc. A quick errand can take several minutes that you didn't count on. Thanks for taking the time to comment.

      This is soooo important Bob. We love our pets but sometimes neglect to do something really important that may harm them...most times accidentally. The hot car is a biggie. When my daughter was young she and I were traveling across country with our dog. We stopped for was a HOT day...I parked the car where I could see it and our sweet TJ...and left it running with the air conditioning on. Well you should have heard the comments from those nearby who had seen us come in and leave her in the car. My daughter spoke up and explained but I DO understand the reaction. Thank you for sharing this. Angels are headed your way this evening ps

      The pet parents I've talked to over the years, who bring their dogs out on errands, truly believe that they're just spending more quality time with their dog. They're gone all day earning their daily bread and feel that when they're not at work they should be with their dogs. They all say, "But I don't do it on a real hot day," but there's no standardized definition of a "real hot day!" Personally, I don't consider 90 degrees to be a "real hot day" but you certainly don't want your dog in the car at that time. I've never read any studies about the subject, but my sense is that it's happening less as pet owners become more enlightened. Thanks for reading and complimenting the hub.


      Thank you for your up-vote, I'm pleased that you enjoyed the hub. You make an excellent point, and one that I wish I had made in the hub. Dogs give unconditional love and they'll still love you as much if you don't take them on your errand run. Dogs have no concept of time, so whether you're gone 30 minutes or 8 hours, they're just as glad to see you when you return. Don't let guilt cause you to make risky choices.

      Regards to you both,

      Voted up, and useful! I don't understand why people NEED to bring their dogs to go grocery shopping with them on hot days! I really get irrated with this. Owner, Fido loves you, but he'd much rather be home with a big bowl of water and a fan than in your portable oven on wheels!

      I enjoyed your hub and I hope the ones who need to know this will read it.

      All pet owners need---is a little common sense. I would never leave my Sweetie Angel in a car alone.

      When I go shopping he stays at home with the a/c in the summer with his dish of ice water to drink.

      He is my baby and that is how I always treat my pet(s) because they are family members also.

      Sorry for going on and on---but people can be dumb as a bag of rocks.


      Your Hub Friend,

      Bobbi Purvis
