I give treats whenever the 3 of them are standing at the gate looking cute!!! LOL Treats around our house are dry hay cubes or apple flax snaps.
One of mine got electrocuted by a set of clippers when he was getting his muzzle trimmed, giving treats is the only way I can trim him. It has taken literally years to get him to suck it up enough to trim him. So treats can be a good thing!
