Dog has fleas, Nexgard gone, chewing fur. What should I do next?

Updated On September 23rd, 2025

Pet's info: Dog | German Shepherd | Male | neutered | 6 years and 9 months old | 69 lbs

It has been determined that my dog has fleas. We took him to an emergency vet last month and got Nexgard for him there (only a 1 month dose). We are coming up on the 2nd month and have nowhere to get more nexgard and his condition has gotten worse as he is chewing off his fur. We have cleaned, used borax, vacuumed every day and washed his bedding. What should we do? This is what his spot looks like now.

You can get Nexgard at any one of our VETCO clinics in your area: ( https://www.vetcoclinics.com/services-and-clinics/clinic-locations-and-schedules/?zip=34639 ) I suggest you use Knockout Spray ES to treat the house and a yard spray to treat the yard. ( https://www.allivet.com/p-1389-knockout-es-area-treatment.aspx?SearchTerm=knockout+Auto ) ( https://www.allivet.com/p-9065-vet-kem-yard-spray-32-oz.aspx?SearchTerm=yard%20spray+Auto ) You can use this hot spot medication on the lesion that he still has on his body. You will need to get him a cone collar to stop him from chewing that spot until you can get the fleas and his discomfort under control. The lesion will not heal unless he stops chewing at it. ( https://www.allivet.com/p-2846-vetericyn-plus-hot-spot-spray.aspx?SearchTerm=hot%20spot+Auto ) ( https://www.petco.com/shop/en/petcostore/product/contech-procone-soft-recovery-collar ) If he doesn't improve then you will need to get him back to the vet for an exam.
