Poor Buster! Yes, from the photos it certainly does look like he has a skin infection of some kind. This can occur on its own, or due to an underlying skin problem such as allergies or mange. I would recommend taking him to the vet to have this checked as soon as you are able to, since he will likely need prescription antibiotics to treat the infection. In the meantime, you can try bathing him thoroughly in a chlorhexidine-based dog shampoo if you like - this should help to remove the crusty discharge and make him a bit more comfortable until you are able to see the vet.

Poor Max! This could be a bacterial or fungal infection or even an auto-immune disease. Since it is spreading quickly, I would strongly recommend to have your vet take a look. He is likely going to need some antibiotics, possibly anti-fungal meds, and maybe even some steroids. Unfortunately, there aren't any good over the counter meds to help cure this. I hope this helps!

It's definitely time to get Cooper into your vet if the affected area is spreading. Issues such as skin infections from bacteria, yeast, etc, or parasites such as mange can be potential causes of crusting, hair loss and irritation. Other issues such as food allergies or metabolic issues may cause similar symptoms. A vet visit along with bloodwork or samples taken of the affected areas can help narrow this down so the correct treatment can be given. In the meantime, placing an Elizabethan (cone) collar or T-shirt on Cooper may help prevent him from being able to scratch the affected area and reduce some irritation until you can be seen by your vet.
