Well I’m not a vet so not 100 sure but it came up on him after coming in contact with a fox covered in mange and I was advised to try Advocate before going vets which cleared it up and I’ve used it ever since and never had a problem atb BB
I used this place
Additional collar of location garmin t5 mini
A top-mounted, high-sensitivity GPS/GLONASS receiver, T 5 mini dog device uses LED beacon lights...
but a lot use gps4us in America
I use the alpha and t5 mini collars I’ve found the t5 collars are over kill and to big and bulky for what we run as there mainly for the American market when there hunts go on for hours and hours sometimes days
