My weak senior dog has demodex. Can't get to vet, what can I do?
Hi, thanks for using PetCoach! Poor Tommy!
How old is Tommy? He looks older. I worry about underlying conditions in older animals that develop demodex. Demodex is only "normal" in young puppies (Immature immune systems). Older dogs that develop demodex usually have an underlying condition that suppressed their immune system and allows the mites to grow. Things like Cushing's disease, cancer, low thyroid, etc. Since you are describing Tommy as weak I am worried about something else going on MORE than just his skin.
There are no good home remedies for demodex. Tommy needs to be examined by a Vet to find out why he is weak and developed the mites in teh first place. You can try a follicular flushing shampoo, bathe twice weekly allowing the lather to sit on the skin for 10 mins http://www.drsfostersmith.com/product/prod_display.cfm?pcatid=21564
Nexgard, Simparica and Bravecto are oral flea and tick medications that also kill demodex. You can see if your Vet will prescribe one of these for Tommy.
I wish Tommy the best!
