Aspen & Willow
“Aspen” and “Willow” enjoy playing, tug of war, and squeaky toys. Willow enjoys swimming and being brushed (and as a puppy, enjoyed chewing on Persian rugs). Aspen especially loves his green plastic football when he can get it away from Willow. They both enjoy running in the yard and chasing birds out of the trees. Aspen is 11 1/2 years old Shepherd mix and Willow is a 2 year old yellow Labrador. You will find them at the clinic most days and they always love to say “Hi” and get a treat.
Sadly, we lost our “Kona” girl to lymphoma on January 6th, 2014 at the age of 11 years old. She is still missed dearly.
“Cali” enjoys sitting on top of the counter and rubbing everyone’s face and knocking pens out of your hand. She was a feral cat that was brought in and was adopted by Cochise Animal Hospital in 2006.
“Cooper” enjoys hanging out in his cage all day, and then roams the front of the clinic at night. He’s a little shy. He was a feral cat and brought into the clinic and was adopted by Cochise Animal Hospital in 2009. You may see him peering through the front window after hours.
