Pet's info: Dog | Maltipoo | Male | neutered | 9 years and 5 months old | 10 lbs

My 9 year old maltipoo has caught fleas. I have tried frontline & other solutions to clear the problem however it still persists. Is Petco Pet Education Center able to prescribe my dog flea medication. If so, please contact me. I'm happy to schedule an online consultation.

Hello. I am so sorry for your worries about the fleas, but it is illegal to prescribe any medications without first doing an in-person physical examination on your pet. So, you will need to see your regular vet about this. There are, however, several things you can still do at home to combat the fleas. One is to add either Capstar, an oral tablet that you can give once a day, week or as often as necessary to kill fleas. The other is to try a Seresto collar. These really work very well & both my options can be used with the Frontline. You also need to treat your home with sprays or bombs that contain an insect growth regulator, & treat your yard as well. There are many very good products out there to combat fleas. It is not often a one time treatment as it can take up to 3 months to eliminate all the living generations of fleas in your vicinity. I hope this helps & thanks for contacting Petco Pet Education Center, formerly Petcoach.
