Well, I can't say if it's an anal gland rupture, or an abcess, but I can tell you that that hole is not, in any way, shape, or form, a normal part of any dog's anatomy. The skin around it looks irritated, and swollen, and the skin damage is causing some hair loss.
Using products made for humans on a wound/injury such as this is never a good idea... he will more than likely need to go on oral antibiotics or risk a systemic infection, which can be potentially fatal. Abcesses, ruptures and puncture wounds are normally left uncovered and allowed to drain as they heal. Bandaging the area will set up an evironment perfect for further infection.
Many times, surgery is necessary to install a rubber drain in the direct area to keep the wound open and draining, and to allow for daily cleansing as the wound/injury is allowed to heal from the inside out. If the outside heals first, that would trap infection inside causing another event to occur... or systemic infection as the bacteria will get into the pup's bloodstream and travel throughout his body.. |
