She is a 3 lb Yorkie and has small black bug on her. I took her to the vet Friday. He said they were dead but wasn't sure what the were had to look under microscope to tell they had legs. He said not to worry my revaluation was working. Well today there are more and they are alive gave a bath still on her. They don't jump like a flea but they are bothering her
JA: I'm sorry to hear that. Have you looked to see if there is a wound on their foot?
Customer: None that are noticeable
JA: The Veterinarian will ask you more detailed questions to find out what is causing this. Is there anything else important you think the Veterinarian should know about the dog?
Customer: Not that I can think

You're speaking to Dr. Michael Salkin. Welcome to JustAnswer. I'm currently typing up my reply. Please be patient. This may take a few minutes.

Can you clarify what "my revaluation was working" means, please? The Revolution (selamectin) was working? I suspect that you're seeing lice - the only other visible black bug other than fleas on dogs. Here's my synopsis of lice for you:

1. Affected and all in-contact same-species animals should be treated.

2. Matted hairs should be clipped away.

3. Traditional therapy is to topically treat your dog's entire body with over the counter 2% lime sulfur, pyrethroids, carbaryl, or organophosphate shampoo, powder, spray, or dip twice 2 weeks apart. Just about any flea insecticide kills lice.

4. Alternative treatments include the following:

Injectable ivermectin given at 0.2 mg/kg orally or subcutaneously 2 weeks apart. Ivermectin is available over the counter in pet/feed stores. Pleas let me know if you need help figuring the dose for your dog.

Selamectin (Revolution) spot-on (as per label), topically twice 2 weeks apart. Treatment administered every 2 weeks at least four times may be more effective. This is a prescription drug available through your vet.

Injectable doramectin given at 0.2-0.4 mg/kg orally every week for 3-4 weeks. This is a prescription drug available through your vet.

0.25% fipronil pump spray (over the counter Frontline, e.g.) 6ml/kg, topically, twice, 2 weeks apart.

10% fipronil spot-on (over the counter Frontline, PetArmor, Fiproguard, e.g.) topically, twice 2 weeks apart.

5. Bedding, grooming tools, and environment should be cleaned at least once. A professional fumigator is suggested in light of the length of time you've struggled with this problem.

6. Prophylactic use of insecticidal flea collars may protect exposed animals from infestation, but avoidance of infected animals is ideal.

The prognosis is good. Lice are highly contagious from dog to dog and from cat to cat, but they aren't considered contagious from dogs or cats to humans. Please respond with further questions or concerns if you wish.

They are very small they do seem to bite her I'm sending a picture which has some hair attached also very had to get off her. If they are biting is my best chance but they are so small I have washed everything. Where would she get lice and why wouldn't a vet be able to identify lice?

Sorry is was revolution was said to be working

I can't get a feel for their size in that photo but they could be lice.

The only alternatives are the Cheyletiella mite ("walking dandruff") and biting midges (no-see-ums). Lice are spread from dog to dog or from infected grooming tools or environment.

The photo image is most consistent with the dog louse Linognathus setosus.

Thank you for your kind accept. I appreciate it. Upon reflection the dog lice Tricodenus canis looks more like the bugs in your photo. I can't set a follow-up in this venue so please return to our conversation - even after rating - with an update at your convenience. You can bookmark this page for ease of return.
