Give the short legged pooches a Capstar after their frapping at the barn.
Capstar kills all fleas on a dog within 30 minutes. Have used it for years on show dogs after having lodged in questionable areas. Can use daily if needed but that will get expensive.
also try this cedarcide.com I have not tried it yet, but am looking into it for both my Corgi - who also loves going to see the ponies - and the cats, who get the gift of fleas from the dog going to the barn.
Frontline and Advantage quit working for us, frontline years ago which our vet said was becoming more common. We stick with Advantix, we have to reapply more often then once a month and in the worst times are applying every 2 weeks, you think horse supplements are expensive, think advantix 2x week for four dogs . This year was a bad year for us, I still don't think I've gotten every single flea, we have even bombed the house as a precaution (which I hate to do since I hate the chemicals but I have little ones who play on the floor etc.) Good luck!!! I hate fleas!!!
Capstar...never heard of it...learn something new everyday. Just to be clear, I read that one dose only lasts 24 hours. It is not long-acting.
Getting pills down the cats is not fun. The dogs are easily tricked.
My vet had me try something that worked fairly well.
Get some lemon dish washing liquid. Fill up a tub with water. Soak the neck area with the dish liquid. Drop the dog in the water. Give the dog a good bath with dish soap. Be sure and apply the lemon soap to the pads of the feet and around the butt.
I was surprised that a few fleas did show up dead. The dogs needed a bath anyway. It's not soap that I'd use constantly, but one or twice during a bad flea season probably won't hurt them.
If you don't want to go the Capstar route, just try bathing them. I guess you can drown fleas and they don't like lemon.
My vet also said that keeping a cup of rubbing alcohol and a Q-tip around works. If you see a flea on your pet, dab it with alcohol and it dies instantly.
We've just gotten turned onto Capstar - love it! Frontline and Advantage do nothing for mine. Mostly, I am looking forward to the weather turning cold and getting rid of all those nasty fleas - they've been especially bad this year!
Back to your original question. I tried the Shoo tags for horses because I have "sucker" branded across my forehead. I didn't notice any improvement at all and they were hard to braid into my horse's mane and did not stay with the magnetic strip facing the right way. Now I don't know how they fit corgis.
A poster here asked me if I would give my opinion of the Shoo tag for an article she was writing. Don't know what her research unearthed, either.
