I posted a question yesterday about my pup being too lethargic for her age and got no responses so I guess no one had an answer or suggestion which doesn't surprise me since my vet can't figure it out either. I've been thinking about it and I'm wondering if she is allergic to her food. She is way too sleepy all the time, finished her antibiotics but still seems off. She has a runny nose all the time and gets the "eye boogers", pants when it is not hot and just doesn't seem to be breathing right sometimes. I thought it might be her food so i didn't feed her first thing this morning just to see if anything would change...sure enough, on our walk she wasn't sneezing, didn't have snot coming out of her nose or the eye boogies and seemed to have more energy. Could she be allergic to her food or is this incident just coincidence? I use Purina One Large Breed Puppy Food (she is 5 months old).
