WE had a horrible experience with MARS. We adopted a puppy that had Parvo and she died within 4 days of our adoption and we spent in total about $3000. Broke our hearts. They are refusing to refund our adoption fee. They are refusing to reply. The bigger issue is that we were allowed to adopt a puppy off of transport and we had no clue she would potentially be contagious. They don't have a quarantine policy or at least they don't enforce it. Never disclosed possible health risks. Told us the vet had looked at her so we would assume that there were no immediate issues. Have read about many good experiences but if you have problems, they are difficult to get resolved.
