Don’t believe it; dogs can get fleas at a kennel

Updated Dec 21, 2021

Dear Cathy,

We boarded our 115-lb. white German Shepherd for 10 days. A few hours after picking him up from the kennel, we discovered he had fleas. The kennel owner said the flea life cycle was 14 days and therefore, my dog could not have gotten fleas during his stay. She said that the fleas couldn’t have jumped from another dog or from the surroundings to infest mine in only 10 days. I’m finding online that fleas can hatch in as little as 2 days in hot humid conditions, which we have. Would you please educate us on how fleas spread, their danger and life cycle?

By the way, my dog had a flea preventative applied about two weeks before his kennel stay. Needless to say, I won’t be boarding my dog there again and not because of my dog getting fleas, but because of the lack of responsibility the kennel owner took.

Dear Sharon,

Fleas don’t generally leave a safe, secure host once they find one, but to say that your dog can’t get fleas during a 10-day period in a dog kennel is simply not true.

Dogs can get fleas from going practically anywhere — the kennel, the groomer, or just playing outside. Fleas can jump almost four feet to find a suitable host for their first blood meal. They may even enter your house by hitching a ride on your clothing or socks.

Having said that, it may not have been a flea, but flea eggs that caused the problem here. Flea eggs can drop off the host and get into bedding, carpets, or cracks and crevices– warm and humid places — where they can advance through their four-stage lifecycle: egg, larval, pupa (cocoon) and adult flea. It can take two weeks to several months to complete the cycle, depending on environmental conditions. That’s because a flea can stay in the pupa stage until a proper host comes along, which is why you can move into a house with no fleas, and your dog may suddenly be infested with fleas a week later.

Fleas can cause a range of health issues, including dermatitis, tapeworms, and anemia. I am not sure why your flea product didn’t work better because a high-quality flea and tick preventative should last four weeks.

No kennel can guarantee there won’t be fleas, but all kennels should make sure pets are on flea preventatives or are treated for fleas before boarding them. Ask a future dog kennel what their protocols are for preventing and managing fleas in their facilities, and always keep your dog on a preventative that kills adult fleas, eggs and larvae.
