This is more for novice members who are considering rehoming a dog into their family, or for families coming together into a "blended" family each with a dog.  Had a Rescue phone call on Thursday evening about a dog needing a new home - couple had moved in together, he had to Staffs, she had an American Cocker (inherited from previous Mother in law)  the dogs had been wary but kept clear of each other for about 3 weeks, but a few spats had started, especially at treat time, or when the spaniel climbed on sofa near the guy.  Arranged for them to bring dog to me on Sunday.   My last words were to make sure they were separate for all  treat times and feeding. Friday morning frantic phone call to say they had had an awful fight over breakfast and the Spaniel was torn up and bleeding.  She had to go to work, had no transport and could not get him to vet.  I picked him up and after some stitches and patching up he is going to be OK, (eye injury and lost tooth among other things) new home already lined up.  But this was so unecessary, just a little caution would hve stopped the injuries, even if they never got on together.  Please, people, don't always assume that because you live in harmony with someone your dogs will too.  Read their body language and pay attention to it.

wise words Gwen > i have often thought how hard this must be we think about children in these situations ( quite rightly ) but know one mentions how animals manage

What ever happened to good old common sense :(

Poor little spaniel. :-(
