Hi there --
Welcome to Just Answer.
I will give you a few examples -- keep in mind though that lice are commonly treated with Frontline very effectively.
This is an adult -- and can be seen with without magnification -- but the features are more easily seen with a magnifying glass.
This is a common appearance in a white dog =-= the dark spots are adults --
The eggs are deposited on the hairs -- and are light in color -
Generally -- treatment with Frontline for 2 months will eliminate this infestation - unless your pet is getting reexposed to an infested dog.
Transmit easily from pet to pet --
Nothing seems to work and her ears are really red. I clean them and pick the black specks out everyday. Are the eggs tiny tiny, round or oval? I see little pepper specks in her ears around her eyes and around her rectum.
The most common small dark bugs that are seen on dogs are fleas (which jump ) and lice --
If you take the black specks -- place them on a tissue and then drop a drop of water on them -- waut a minute and rub slightly -- do these dark specks bleed out reddish brown ?
I am wondering if these are either flea dirt --
Or (since they are near the ear) is there a chance of ear mites (which cannot be seen -- but their droppings can ) ?
The eggs are barely visible -
can be more esily seen with mild magnification --
Mites need a skin scraping and microscope to be seen -- and ear mites generally stay in the ear.
Most common forms of these will respond to Revolution topical fleas preventative -- except for demodex mites (which this does not sound like -- as typically this is areas of hair loss) .
The ears may be infected with bacteria and yeast -- which is common - and can give the red inflammed appearance --
also -- allergies will show up in dogs this way -
This is also supported by the licking and biting at her feet -- allergies (atopic dermatitis) will show up this way .
One other thing -- often a single flea bite can trigger in allergic reaction in a dog that is allergic to flea saliva. This is one of the most common allergies --
Since there are a few possible considerations, a vet visit may give you the best diagnosis so that treatment can be started.
