Ever since I bought a mixed breed pup online in April, forum members have mentioned the perils of so-called designer dog breeders. I finally get it . . . and here's why: Alvin is a handsome, sweet hybrid pup but his list of health issues continues to grow longer and more serious: 1) Pup arrived with a UTI 2) Pup arrived with an intestinal parasite. 3) Pup has been itching and scratching since day one and is being treated for allergies. 4) And today, the vet looked at pre-surgery (neutering) blood work and called with the news that he suspects the congenital condition liver shunt (may be the reason for 1 and 3). We are all upset about the diagnosis even though it has to be confirmed with another blood test and if positive, an ultrasound. What a shame such a loving animal must suffer the consequences of bad breeding practices. He is and will continue to be well cared for. And how uninformed were we to get a hybrid pup online?
