A couple came to my Lurcher Racing yesterday from the Lurcher Link charity and they had 8 dogs in the van and their doggy first aid box was very imressive.After racing they syringed 20ml of a horse electolyte into their dogs mouths.They said it was like the dogs one but a lot stronger and dont need as much.And also had a good muscle rub they used.I will try and find out the names of both they used for you, i know the horse electrolyte was called Apple ?something? and the mix was a teaspoon to a litre of water.Ill yry contact them now for you.
