Hello and thank you for contacting Petco Pet Education Center, formerly Petcoach. It is always very hard to make diagnosis by looking at pictures. I suspect that the black dots are small wounds from insect bites or self-inflicted trauma, if Happy has been licking and biting herself excessively. Please, use a soothing oatmeal dog shampoo for Happy and 2-3 days later apply a good quality flea product. If that doesn't help, you should take her to your local vets to check her over.

    Hello, and thank you for your question. The black patches look like they could be benign skin tags or warts, or sebaceous cysts. I would still have them checked out by the vet, who may recommend a fine needle aspirate to confirm what they are. Often times chronic itchy skin can result in hyperpigmentation (the skin's response to chronic inflammation), so I would not worry too much until you get it assessed in person by the vet. I hope this helps, and that your vet visit tomorrow goes well!

    This is probably caused by an allergic reaction. first of all make sure you de-flea Tika regularly every month with a high quality spot on (ex. Advantage) as fleas are by far the most common reason for these reactions. If the fleas are not the problem, it could be an allergic reaction to food or an environmental factor. this is more complicated to treat and will sometimes require medications such as Steroids, anti histamines or cyclosporin in order to stop the allergy.
