Doberman puppy under weight
Question for all your Doberman professionals out there we recently got a Doberman about a month ago. He is currently 12 weeks old. We took him in today to go get his ears cropped. They did a blood test and they came back and said that his. Red blood cell count was high, his BUD was low, and he’s a little underweight at only 18 pounds of 12 weeks. When we first got him at eight weeks, he was 10 pounds within the first two weeks he put on seven. We recently switched up his food. He seemed to be doing OK on the first food, but we wanted to try a different kind of food. The first food we tried was (ACANA Puppy sea and farm) like I said, he seemed to be doing good on this food. His coat seemed good. Then over the last week and a half we switched it to (Open Farm- Puppy salmon and ancient Grains recipe). We would feed him three times a day at round a cup each may be a little less than that. I’ve noticed over the last week and a half. He has started to tantrum during crate training, not just whining like full-blown meltdowns and it would take him anywhere from seven minutes all the way up to the longest one hours to calm down. I mainly looking for advice on what to do if this is a food problem any recommendations for food to have a healthy Doberman. I just want my sweet boy to be happy healthy, and well.
