Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | unspayed | 11 months and 5 days old | 25 lbs
My dog has a open sore I just discovered behind her collar right above her front left leg. Not sure what has caused this. She's an indoor dog and is crate trained. She has never been exposed to any external elements that would have caused this. Not sure what to do

Sorry to see what's going on with Marlee. The first thing that you need to do is shave all the hair on and around the affected area. After doing this, you can use an antiseptic solution like chlorhexidine or dilute betadine to clean the lesion and the surrounding tissue. This will give you a better idea of how it looks. Based on the picture alone, the lesion looks pretty infected. You can certainly try to treat with just the antiseptic and a topical antimicrobial / steroid, but this may not be enough. In cases like this, many times an oral antibiotic is required to help clear this up. You will also likely have to put a collar on Marlee to prevent her from causing further damage to the area her self. Hope this helps.
