This happened to our dogs. Even though they are both fixed they still get urges... lol

My female dog hates being harrassed by the male for special attention. So they fight... ( silimar situation inside the house... PMSL) . He tries to and she isnt interested so she gets fiesty and then its all for nothing. They appear to be vicious but never have they really hurt each other. I wet them when they go for it. and ALWAYS supervice the kids with the dogs. JIC. (i dont care what breed i think supervision is a must.)

We have a kelpie and a lab and our lab is a hoover. Loves his food. So we have to seperate at meal times also. they can get along well for a while but they fight almost daily... Try wetting them. Also i heard that a bit of vinegar in the water makes it taste yuk so when they lick it off they dont like it so they stop... Not sure have never tried vineger. Hose is always quicker to get... lol.
