hey, Beagles dig alot and have a very good sense of smell, i was told this is a dog that needs to be taken out alot walks etc.(a friend of mine was going to get one) but got turned off by the digging problem.
West Highland cute little dogs need to be brushed everyday you could probley get away with every second day.
not sure about the other breeds, my advice would be to email breeders of the type of dog you want they are the best people to talk too.
