in north central Fla. we have a lot of flint rocks in the woods. some of them have razor sharp edges.
all of my dogs get cuts and bruses.befor the season I will mix in a large coffee can 1 ga.???I think I mix 1 lb. of salt and 2 to 3 quarts of white vinigar.
I take each dog and stick there paws into this solution for a min. this will toughen there feet and leg as far as it goes into the mixture.

if they already have a cut,it will burn some , but also heal the cut in a few days.in all the years I have run dogs in the rocks,I have not had one lame for over two ot three days.when I say burn some,( when you turn them alose)get out of the way.they will roll and rub all over the house.unless you do it in the kennel.

this mixture is the best I have found,(even from the vets).I have been useing this for about 30 to 35 years.with great results.
