What are these red, crusty bumps on my dog's skin? Is it a hot spot?

Question

Hello. I have a one and a half year old dachhund dog. A week ago a noticed a round crust on its skin in front of the neck. In a few days multiple smaller spots of crust appeard down to the axilar area and some up to its neck. I didn't noticed to be itchy, the dog doesn't scratches more, eats well, the hair didn't fell down around the area, they are slightly red coloured and like a bump on the skin, some bigger than others but not bigger then half a centimetre diameter. Please help us. Thank you. Pet's info: Dog | Mixed Breed Small (up to 22lb) | Female

I am so sorry to hear that Tasha is having trouble with her skin. It is difficult to know ahh the initial lesion was, parasites, fleas or even a skin allergy. However, when a dog has irritated skin they often react by chewing or licking their skin. This causes tissue trauma and can introduce infection. This leads to moist dermatitis or "hot spot". Hot spots can be very difficult to heal, and take a long time. The keys to a successful healing process are; Treating the underlying cause -for example fleas A clipped area around the sore Cleaning the sore with a vet prescribed antiseptic Leaving the sore open to dry out (as the moisture promotes bacterial growth) Antibacterial/ hydrocortisone spray prescribed from the vet for healing An e-collar to prevent Tasha from scratching or biting at the hot spot and making it worse Measure the hot spot with a ruler, and compare in a few days time to make sure that it is reducing in size. If you feel like Tasha is not healing well, I would suggest a trip to the vet for the above mentioned medications, or call and discuss the possibility for a prescription. Oral antibiotics and/ or a steroid injection may help to jumpstart the healing process. I know hot spots can be very frustrating for you as a pet parent and for Tasha. I sincerely hope it starts to heal soon. Warmest regards to you both.
