As you found out there are only a few places around denver with ultrasound. Our Vet was going to send us to Mountain Veterinary Imaging, LLC for a cardiac ultrasound. Unfortunately he died before we got there of a congenital heart defect. They have offices in Loveland and Windsor.

One thing that concerns me though is the your Vet should have set up the referral and appointment. These type of clinics usually only work on referrals. Maybe you need a better primary Vet?????

Good Luck
