@Knipper:
Blaze hates small furry dogs. He catches them, pins them down and rips out their furโฆ if I'm not quick enough.
He loves big dogs! Rotties, Dobbies, german shepards, great danes, golden retrievers, and one 1/4 wolf. He tires them out, then pees on them triumphantly... You might have to watch out for that...
Tucker is the same way. Smaller dogs are 'prey', larger dogs are his choice with regard to playmates, it seems. We've only recently begun his dog socialization regime but all of his bestest dog pals are labs, a boxer, a rottie and some larger mixes. Whenever he sees a small terrier or the like, he just wants to eat them.
