Perfect for bites aswell, first time we discovered it was when a staff pup had surface gang green. Misses also had it prescribed for sariasis. Great part of any working dog medical bag.
Jreid and hedz are spot on IMO, why keep something not doing what is required? If the animal is a pet firstly and a worker secondly then fair enough keep it if it's crap but if it's only role is to work well I can't see the point keeping crap
