Why is my dog acting strange with skin holes after flea treatment?

It could be possible that Jett may have a problem with his anal glands, or another skin issue which is causing his irritation. I would recommend making an appointment with your veterinarian to have him examined fully. Your veterinarian will then be able to suggest an appropriate course of treatment which may include antiinflammatories and antibiotics, particularly if he has broken the skin barrier.

Looks like your little lady is giving herself some hot spots there. If there is a hot spot forming under the hair then the best thing to do is to remove the hair and cleanse the area with an antibacterial solution. Some dogs require topical and/or oral antibiotics and other dogs benefit from some steroids to stop the itch. Most hot spots are secondary to underlying allergies (inhaled/environmental, food, or flea). If seasonal environmental is most likely. The best way to help her would be to see your family vet to have the areas addressed topically and so that medications can be prescribed to treat any infection and stop the itch. I hope this helps and thank you for using Petco Pet Education Center, formerly Petcoach!

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.

It's possible Bam Bam has developed an allergy (it could be environmental or food related) or that his thyroid is having problems. Unless you are treating him with a very good, oral flea prevention, fleas should still be on your list. This behavior of suddenly jumping up and biting is very commonly associated with flea bites. At home you can try giving him an omega 3 fatty acid supplement for pets but it may not correct the underlying cause. This can however improve over all skin health. There are two brands of food, Royal Canin and Nutro, which are aimed at skin health and they may help as well but again, they may not affect the underlying problem. If he does not improve after 2 weeks, I think your best option is to have him examined by the veterinarian. I hope this helps and please feel free to post any additional questions.

There is a possibility that he is irritated from flea bites at his tail and/or from the spot on. It is a well-known side effect that spot-ons can cause an itch, hair loss, irritation, but usually that irritation is gone within a few hours. Do not let him bite or lick or scratch the application location. You can put a loose t-shirt on him covering up the location or put on an e-collar. If the irritation has not subsided by tomorrow, or if Boy boy develops a wound , he will need to be seen by a veterinarian for an exam. In the meantime do not put cream or ointment onto the location where you applied the flea treatment.

I would use this medicated mousse on him for a week or so. If no improvement or if he seems worse then get him to your vet for an exam. ( http://www.allivet.com/p-6679-douxo-calm-mousse-for-dogs-and-cats-68-oz.aspx ) Hope this helps. Best wishes.

Hello and thank you very much for your question. Fleas can be so frustrating and I sympathize with what you were going through. What has to happen for your dog to heal and for the lump to possibly go down, Is for the itch cycle and the inflammation to be stopped. A visit to the local veterinarian is a must in this situation because they will have strong prescription strength flea preventative as well as steroids that can be given to your dog to stop the fleas and therefore the dermatitis that’s associated with their biting. I urge you not to use any further over-the-counter flea preventative or skin medications without the approval from your veterinarian. This will only delay the healing and may exacerbate the problem. The lump should go down with time as long as the fleas are killed and the inflammation of the skin is controlled. But, if the lamp does not go away within the next two months, you may want to have your veterinarian take a biopsy of it just to see if it is indeed even related to the fleas. Does that make sense? I appreciate you reaching out to our service. I hope I’ve helped you today.
