I am seeking advice really. My labs leg began swelling two weeks ago. We took him to the vets and he was given steroids and antibiotics. Over the last week the infection in his leg has become increasingly worse and he is now having trouble breathing. We took him back to the vet and they said he may be having a reaction to the tablets. He is still eating although in stages, he is still going to the loo but is exhausted when he gets back. He's not wimpering with pain from his leg but we just cant work out how a leg infection can lead to this. Has anyone experienced a dog having a bad reaction to tablets. I have googled so many things but even the vets are baffled as to what it could be. He is going in tomorrow for a chest scan and to be operated on the leg as it is still weeping and he is holding a lot of water. He has had all sorts of tests and all have come back clear, no organ failure, bloods are good, he just looks and seems really wiped out from the infection and the tablets haven't improved anything. We are hoping if he is sedated they can open the leg up and see what is going on. Anyone ever experienced anything like this? We are worried sick. Its heartbreaking to see him so unwell. He is only 9 and before this was happy, healthy and lively
