Our lovely 5 year old boy kipling the whippet is ever so poorly. he had a really bad cough and dropped weight so fast, all his ribs poked through within a day, no tummy left, and unable to walk far or sit / stand without effort. he had seemed lazy for a few days before but because we had him neutered a few weeks back we thought he was still a bit quiet. he went to the vets who kept him in for a couple of days and sent him back saying they didn't know what was wrong. he was on antibiotic and pain relief. after a day or two at home he wasn't better so we took him to the PDSA. they said he had heart failure and wouldn't live beyond 6-12 months. we got him back after a day, he'd been on a drip, and he had heart pills and antibiotics. He didn't seem better apart from a couple of mornings where our hopes were raised. Then he got really poorly. We took him back to a second vet at the PDSA who said he has an infection which is attacking his internal organs. He's now on other antibiotics and the same heart pills. He started them on Tuesday and started looking a tiny bit perkier after a day. Today he has his head raised on a couple of occassions and looks a bit rosier. can anyone help?
