Dog scratching after flea meds. Is it allergies, mites, or fleas?

Fleas live in the environment, not on the dog. They just on the dog to feed, and jump off when done. If you haven't disinfected your home, that may be why Sunnie is still itching and you are starting to itch. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. If this doesn't help, then I'd be concerned it could be something else contagious going on like mange or ringworm. Then I would take him back into the vet, and have you see your doctor. Best of luck.

When you have a heavy flea infestation, you also have to disinfect the environment as well. Wash theirs bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. Dogs who have heavy flea infestations can also develop flea allergies, which would lead them to continue to be itchy and may affect the fur growing back. I would take them both back into the vet, and the vet can discuss if they do have flea allergies and how to treat them. Tonight, give them baths in Epsom salts or oatmeal, as it may help temporarily with the itching. Tomorrow, I'd take them into the vet. Good luck, I hope this helps!

Poor King! Sometimes fleas can be hard to find, and the only evidence of them is flea dirt (little black specs that is flea poop). This scratching can be caused by fleas, mites, ringworm, or allergies. If he isn't up to date on his flea treatment, I can give you one for him. First, I would give him Capstar. It's a one time pill that starts killing fleas within 30 minutes. Then follow up with a spot on treatment, such as Advantage or Revolution. This is a treatment that has to be used once a month. You will also have to disinfect the environment. Wash his bedding in hot soapy water, and vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. If he is up to date on his flea treatment, I recommend taking him into the vet for an exam tomorrow. The vet can do blood tests, skin scrapings, and use a Wood's lamp to diagnose allergies, mites, and ringworm. Once the cause of the itching is found, the vet can prescribe the appropriate treatment. I hope this helps!

Trifexis works by killing fleas when they bite your dog, but they don't repel fleas. If Dallas is still scratching a lot, fleas could be getting on him from the home, or he could have developed a flea allergy from a previously heavy burden of fleas.

I would also take Dallas into the vet to discuss the continued scratching, as he may benefit from medications such as steroids if he has a flea allergy.

If he has a flea allergy than it will probably take a little bit of time for the itching to resolve. You could ask your vet for an anti-histamine or a corticosteroid to help relieve the itching. Make sure to use a monthly flea prevention, like NexGard, Frontline, Advantage, etc every month to prevent him from getting fleas again.

Allergies, either to something in the environment or less often to food, would be the most common cause of itching if Charlie is on a prescription flea preventative. He may have a secondary skin infection as well since you are feeling bumps. Mange can cause hair loss but usually isn’t significantly itchy.
