I agree Rank might not be good, but Topfield is nice.
Thing is anything fairly obvious may already be taken by Someone else.
If you go onto the kennel club website I believe you can use their name checking facility to check that a choice of name (which includes kennel name) does not conflict with someones existing kennel name.
You can also write down a list of choices and contact the kennel club and ask if they would check that they aren't already taken.
