Meet Onyx

Meet Onyx!
Onyx is a friendly, rambunctious, good natured and energetic 3-year-old dog. He has lived with grade school kids who loved him, and currently lives with teenagers and another dog.

He gets along with dogs but wants to play so much that he should only be with dogs who still want to play. He would be a great friend for another dog that wants to play and wrestle, but not great for older dogs or dogs who just want to hang out and sleep. He currently eats his meals in a kennel or a separate space from other dogs due to some resource guarding. He has been able to sit next to other dogs while working on training commands for treats with no issues.

He lived with cats but needs to be kept separate from them while his people are not home because he wants to play so much, he cannot back off. He should only go to a home with dog savvy cats and away to keep them separated when needed.

He is 70lbs of muscle but still thinks he is a lap dog and would like to hang out with his people on the couch. He will jump up when excited, his foster family is working on “off” and “down” training.

Onyx is house trained, crate trained and knows some basic commands like sit and shake. He is walking well on a leash using a Gentle Leader style harness; he has a strong prey drive and will pull if he sees anything furry. He sleeps in a crate at night and is crated during the day when no one is home.

He likes to lay in the sun or the couch and has had fun exploring his foster family’s backyard.
