Just wondering if any of you lads on here have seen these symptoms in any of your dogs before. I woke up this morning to find the lurcher pup having trouble breathing, his breathing was shalow he was also weak and his eyes a bit glazed. So i took him to the vets and she done chest x-rays and said she couldnt find what was wrong with him so she gave him anti inflamitorys and anti biotics and said that if it dont get better in a week to take him back. Any ideas!!
