Thanks to everyone for all the responses. You pretty much confirmed what I already knew but some times it helps to hear it from others. The overwhelming conclusion is that spaying will not make a difference and the only way to ensure this won't happen again is to keep them separate. BTW this bitch has never been aggressive and is actually very sweet which was why her attack on the other bitch was so unexpected. She also shares the house with two other males with no problems at all. I'm not frustrated with the dog, it's the owner who know's the difficulities in keeping two bitches in the house and yet won't even consider trying to come up with an alternative for a problem that she may have very well created herself. <sigh> Cindy Pinehillgsds@xxxxxxx wrote: In my opinion, once bitches take a dislike to one another, they can't be trusted together again. And, if they DO go at it, it won't stop once one of them says "uncle". There is NOTHING worse than a bitch fight! Spaying the youngest bitch will have absolutely no effect. (And this is from someone who has a house full of intact males who know how to behave together, so it isn't like I tolerate nonsense <G>.)
