How to get rid of stubborn fleas on my dog when nothing works?

Updated On September 23rd, 2025

Pet's info: Dog | Australian Shepherd | Male | unneutered | 10 months and 26 days old | 16 lbs

My 11 month old mini Australian Shepherd has had fleas now a couple times. We got rid of them and put a flea collar and it seemed to work. He then go the fleas again and now we can’t seem to get rid of them with the collar or the ointment. Do you have any suggestions on what will get rid of them? We just moved from a neighborhood with stray cats which we believe is where the fleas were coming from. We now live somewhere with less fleas and we just want them gone! Thank you!!

I can give you a flea treatment program for Charlie. 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. I hope this helps!

    It sounds like Charlie is itching if he's intensely licking his back leg area. This itching 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 this weekend or on Monday. 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. To keep him from licking more, I would put an Ecollar on him. You can make one at home (I will put a link below on how to do it), or you can buy one at a pet store.
