Animal Care Needed

I am looking for a border for my two dogs while we go on vacation at the end of July. My preference is for an experienced border and will introduce my dogs to other dogs with care. I have concerns about dog fights and want everything to go smoothly and for it to be a good experience for all. I have a female black lab/aussie mix (7) and a male border collie (5)... will be 6. They typically get a lot of walks but would be just as happy for a backyard to play in the morning or evening when it's cool. The border collie has an eye condition that requires eye drops twice/Day. My lab is food aggressive and needs to be kept away from other dogs at meal time.
