Coliseum de Cassiope reports to performing the health tests below on their breeding dogs. Ask your breeder about the tests performed on the parents of your litter. Learn more about health testing for Cane Corso.
Hip Dysplasia
Hip testing reduces the chance of passing down hip dysplasia, which is primarily found in large breed dogs and can cause hip pain and the eventual loss of the function of the hip joint.
Cardiac Evaluation (registered with OFA)
Heart testing reduces the chance of passing down congenital heart disease, which can cause a range of symptoms ranging from trouble exercising to heart failure.
Patellar Luxation
Knee testing reduces the chance of passing down Patellar Luxation, which results in the kneecap becoming displaced or dislocated and can cause mild to severe joint pain.

Karen has been an absolute pleasure to work with. Her deep knowledge of the breed and dedication to the health and wellbeing of her dogs truly set her apart. She was consistently responsive to messages and kept us informed with regular updates throughout the entire process. Thanks to her care and expertise, Moss is now 5½ months old and thriving—and we’re enjoying every moment with him

Karen from Coliseum de Cassiope was absolutely amazing to work with prior to Max coming home with me. She was so well-versed and knowledgeable about the breed, and it was clear how much she cared for her dogs. Her dedication to their health and well-being was so reassuring. She was incredibly well-caring and went above and beyond to make sure I was kept up to date on Max's progress. I couldn't be happier with the experience and would highly recommend her to anyone.

Karen was absolutely wonderful throughout the whole process. She answered all of our questions, sent us pictures and udpates of our puppy and was so easy to work with the whole way, all the way to pickup of our puppy. We would definitely get another dog from her down the road if we were looking again. And Cupcake, our newest pug puppy is an absolute angel, already seemed potty trained and is doing wonderful. Thank you so much Karen!!!

Karen was amazing! She was quick to respond and answered any questions I had. We even had an accidental mix up and Karen was amazing and still made the pickup happen!

The whole experience was professional, educational, and loving. I can tell how much love Karen gives to her puppies and I am fortunate to have found a great breeder. We received our new baby boy with everything we will need to make sure he grows into a healthy dog. Thank you so much for making this a wonderful experience.

We cannot say enough good things about Karen of Coliseum de Cassiope! She was absolutely incredible to work with as we were looking for a new pug puppy. She was so responsive, which we valued a great deal because getting a puppy is a big decision and we had lots and lots of questions. Karen answered everything in such a timely manner, and she went above and beyond in sending us photos/videos each Sunday which we really enjoyed and looked forward to getting leading up to our delivery date to us. She set up an amazing flight nanny for us because we live in Los Angeles and it made getting our puppy, Apollo, just so easy. She sent along all the necessary paperwork and even a bag of goodies, too! Karen took such great love and care in getting Apollo ready for us. He was very well behaved, litter box trained, we think (?) he knew his name, and all of this is extremely helpful. Apollo is happy, smart, playful, curious, snuggly and very sweet! We would totally go to Karen in the future should we ever get another pug puppy, and highly recommend her as a breeder!
