demodex.....

Question
hi my name is jo,
i have a 3yr old bulldog with demodex....for the most part i have it under control with medicated shampoo...in the summer time it tends to flare up... i was wondering if you have any suggestions as to what i can do with him to help keep it under control at all times...i have spoken with a vet, he is now retired, the new vet wanted to put him on injections which i did not feel comfortable with, would you know of any possible oral solutions for demodex.... i know its only your opinion, but from what i have learned it really seems other dog owners sometimes can help more!

Answer
Hi Jo-

Its interesting that the demodex is flaring back up so much when he is an adult. Adults dogs should not get demodicosis unless there is a serious underlying condition with their immune system or possibly kidneys.

Let me explain a little about the demodex (Pardon if you are aware of all of this) Demodex is caused by tiny mites that live on your dogs skin. Now, all puppies get these mites transfered to them by their mother, and most dogs live with these mites forever in perfect unison, having a very symbiotic relationship. However, if something happens to the puppy and its immune system is compromised, then occasionally the mites can get out of control and cause the classic demodex pattern. However, in adult dogs over 18 months, demodicosis is considered an indication to seek a more serious hidden condition such as cancer, liver or kidney disease, or an immune-suppressive hormone imbalance. A more extensive medical work-up will be required by a vet to see what is causing the supression of his immune system.

There are a few treatments that I am curious if you are using. The first is ivermectin (Note: For anyone else reading this article for help with their dogs, DO NOT give ivermectin to a herding breed such as a collie, sheepdog, sheltie, border collie, etc unless you KNOW you dog is not ivermectin intolerant, it will KILL your dog) which can either be given orally or injected. This is a great broad spectrum anti-parasitic medication that really helps, and its also fairly inexpensive.

The second, and most time honored, is mitaban shampoo. I am guessing by medicated shampoo, you mean mitaban. If not, then I highly suggest using mitaban, and also perhaps doubling up with ivermectin.

Remember to CONTINUE THE ENTIRE COURSE of medication, even if your dog appears better. You have to kill ALL the mites, or it will just come back in 6-12 months!

I hope this helps a little!
