My corgi weaned a litter of puppies the beginning of July. She was a bit underweight but was eating well and drinking well. Toward the end of July we began to see an increase in her abdomen. After ruling out gorging and uptake in water intake, we took her to our vet. She has significant distention of her abdomen but no other symtoms. She is not lethargic, still wants to be a part of our ball throwing and running each night. Our regular vet says that her heart sounds great, no signs of parasites, etc but her bloodwork shows that her protein and albumin are low. Sample of the fluid from her abdomen doesn't show any type of infection and all other bloodwork is normal. We have a referal from our vet to specialty clinic and have the earlies appointment scheduled for further testing, xrays, and ultrasound but I am trying to find out more of what may have caused this and what to expect at our appointment. The only difference from her first litter to this one after weaning is an obvious change in the texture and color of the dog food that we normally buy. No change in ingredients or percentages but a definite change in look, texture and smell. I have since quit feeding her the food and changed it. It may be wishful thinking but I believe there is a slight decrease in her abdomen since the switch.
