We didn't do much research on caring and training a puppy until after we rescued one from a shelter and probably rushed the adoption more than we should have. We were taking advantage of our current time off while waiting to go back to work during the pandemic and felt the sooner we get one the more time we have to train one. Most of the shelters by me were closed to new adoptions and there was really only still doing them so our options were limited. Now that we have him we will care for him well and even hired a puppy trainer to help us. He is a handful but also loveable when he is behaving. I do know now that he was probably taken from his litter way to early because we adopted him when he was 8 weeks old and was probably in the shelter for weeks already missing out on important skills taught by mom and litter mates adding to some of the behavior issues we are trying to correct. Also we did a DNA test and the health portion reveals one gene variant for joint and spinal issues which we will monitor but most concerning is the 26% COI. I found out that this is extremely high. How concerned should I be and does anyone have positive experiences with a pup that also has very COI? We will keep him whatever the case is.
