Aut cum scuto aut in scuto
Able to leap tall fences in a single bound!
Givin' the fence a slippet. There goes that whippet
Should be teaching the deers.
Who needs a running start? Not me.
Spring loaded hair trigger
Might be a galgo - they love to bound and they look very similar to greyhounds but slightly smaller. Salukis too, I've seen them let out and they just leap like this little guy did, out of pure joy - no fence required.
