This is what a flea looks like, and it’s disgusting

You definitely don't want these gross bugs to take over your house and bite your pets

We could have gone our whole lives without seeing a flea up close under a microscope — they’re terrifying! Most of the time, when you spot a flea, it’s outside in the grass, or unfortunately, on your dog or cat. It’s not pleasant, but at least at such a small size, it’s tricky to make out any kind of identifying details (imagine if one of these creatures was actually large enough to look at without magnification assistance).

While it might spook you to take a look at a flea up close, you should be even more concerned about spotting them in the wild, where they might be snacking on your pet and infesting your home.

What do fleas look like?

If you gaze upon the close version of this insect, you’ll spot the telltale six legs, brown or reddish body, and tiny needle-like appendages for sucking blood (fortunately no wings). Instead of flying, these little buggers jump from person to pet to grass. They feast on blood from mammals, so they’re coming for you and all your furry friends. To the naked eye, you’ll likely spot a tiny blackish speck that could be deep in your dog’s fur or even crawling on your floor.

What do fleas do to pets?

Mostly, eat them. As with other biting bugs, they inject a bit of anticoagulant in order to keep the blood flowing —  that’s part of where the itchiness comes in. You’ll notice red spots and lots of scratching if they wind up on your dog or cat. These pests can also cause other more serious problems, such as tapeworm and anemia, so you want to take care of this quickly once you discover the infestation.

What treatment is available for fleas?

Luckily, a little maintenance usually prevents these parasites from moving in. You have a few options to use as a preventative, including oral, topical, or removable. Many choose to give their pets a chewable or a pill (and some combo pills are available that tackle multiple freeloaders at once, like heartworm and fleas).

Alternatively, look into collars that can come on and off as necessary or a gel that goes on the pet’s back. As with all medications, carefully follow the instructions. You don’t want to give your little guy too big a dose, which can cause sickness. If the fleas do set in, you should also look into shampoos and combs to tackle the issue.

In your house, you need to follow regular cleaning routines to ensure fleas stay out and don’t wind up living in your home between meals. That means vacuuming all carpet and washing pet bedding or pet clothes consistently, including blankets and sweaters. Remember that even if your animals have been treated, they still might come into contact with these bugs outside on walks. Fleas can easily hitch a ride and then find another unsuspecting critter in the house — for example, a dog could accidentally bring fleas in that then grab onto an indoor cat. We actually recommend treating all fuzzy household members even if they don’t spend any time around bugs themselves.

Your dog is more than just your constant companion; he's also a beloved member of the family. No matter the season, frequent exercise, a well-balanced diet, and outdoor playtime are essential to your dog's health and happiness.

Not only does exercise prevent obesity, but it also provides the mental stimulation your pup needs to lower the risk of mental health issues, such as depression and anxiety. We're all aware of the potential dangers of overheating, but what should we do when temperatures drop? At what point is taking your pup outside for a walk more harmful than helpful?

Video: Dog meets Santa for the first time (and it’s super heartwarming)

For so many, the highlight of Christmas was meeting Santa and asking for presents. That early memory of sitting on "the big man's" knee or watching your children see him for the first time is something we carry around. It's not just the kids who love the jolly fellow, though — some pets also jump for joy upon seeing that red suit. We love a good cheerful dog video this time of year, and the pup in this one will surely make your heart melt.

Huey the Blue Staffy, who himself lives in Staffordshire England, has amassed quite a following on Tik Tok, including many darling Christmas videos. But none are better than his first intro to Santa Claus set to the iconic Theme from Elf (the Will Ferrell movie, that is). Huey frequently dons a festive sweater, and this adventure is no exception. Entitled "When Huey the blue staffy met Santa for the first time | Can’t wait to see his reaction this year!" it doesn't disappoint.
In it, he sports a "Merry Christmas" jumper complete with red and green. You won't believe how hyped up this sweet doggo gets when he lays eyes on his new best friend, Santa. After excitedly pulling on the leash, he finally gets to meet Kris Kringle and even gets a few pets and hugs. Santa ends the encounter by giving the precious pup a belly rub as well.
However, this is actually a repost from last year and we get to see Huey revisit his favorite time of year with a cute photo of him and Santa. Don't worry, his dog mom posted this year's encounter, including Huey's intro to one of the famous elves as well.
