I have had a number of different breeds.
Beagles
Labs
mini poodle
collie mixes
heeler mixes
JRT
Lhasa/JRT mix
2 Podengos
Schipperke (briefly)
GSD (briefly)
Pitt Mix
Not to mention dogs i've worked with of many different breeds.

Of all the dogs i've had the two that truly touched my life the most were the mini poodle (possibly circumstance) and Caesar my male Podengo/posible mix.
I believe had I gotten Caesar as a puppy vs. a young dog that he would of been my "dream" dog , hes working on but adult dogs typically have baggage.
