One dog supposed to have a hold on the other dog, generally the case, so I give this as a sample. A pail of water will in many cases make the dog let go - for a minute or less, but in some breeds, as Bull terriers, or Airedale terriers, this will not work. You might, if strong enough in the hand, choke the one dog off, but in cases of Bull terriers I have failed, if you had a bottle of amonia right there, this would make any dog let go - for a minute or so only, if it was a Bull terrier. What will make any dog let go is a lit cigar held to his nose, or, a burning match may do if no lit cigar is handy. The trouble now comes up, after separated, that one or both dogs will get right at it again, and here is where you must have a level head, and your nerve, to prevent this. One person alone will have a contract on his hands, but if there happens to be some other sensible man there to assist, each one of you grab a dog by his collar, or, if no collar on dog, then by the nap of his neck, and hold your dog back. I have separated dogs alone, by holding each one apart at arms length, but it's quite a job. A dog can't bite you, if you keep your head, not afraid or scared yourself, when you have a firm hold on his collar, on top of his neck, or by the nap of his neck, on top. Neither dog in the fight is wanting to bite you - it's the other dog he is after.

Now see in this book, "Bites," as to how to treat them if dog is bitten, or you might be.
