In terms of fire ants and any bug bite pain, i guess not every vizsla indicates the pain the same way: Bende would run up to mom and shake his leg, asking me to remove them. Miksa (the younger one) would just stand in the middle of the fire ant mount and once we go home i would discover that his lower part is full of the white puss outbreaks. Interestingly treating it immediately with silver colloidal and 1-2 more times, they pretty much disappear within 24-48 hours from him.
i would be interested also about experiences in terms of hair grow back: Bende had a sebaceous cyst on his back and it erupted during our last hunt test. I treated it to ensure it does not get infected. Once the scar was fully healed u would still see a bold spot. Then i started putting castor oil on it and it is now halfway covered by hair again.
