I used to have a lurcher cross when I was a kid. He used to love to swim in the sea. Loved it. He was highly strung but that was just him. Whippets are fine dogs. I keep terrier's and they would happily come wherever I go if they could cause they don't seem to ever get tired. Always a new hole/bush to poke you're head in. That sound's dodgy but I can't explain it any better. Sludge you will be in you're element mate. Always a dog ready to be rescued and give you everything they have got in return. If you got the time then you are in there mate. Plus they can't complain to you about you're taste in music. Hope it works for you
