I have been observing one of my girls for a while. She had a few bite wounds throughout her body due to the rough and tumble both of my Bs engaged in. However her wounds take a long time (roughly 2 week or more) to heal. Initially I did nothing, thinking the superficial wounds would heal pretty quickly. I kept brushing my hand over her body daily and I would still encounter the bumps. I applied medical cream over the wound to hasten the recovery process and the wounds healed a few days after I start applying the cream.
I like to ask how long your Bs take to recover from their bite wounds
