Our 9 year-old lab has been under the weather for about three weeks but two different vets (one when we were on holiday) have said it's just a cough and he'll get over it. The holiday one (about 10 days ago) said he was really healthy apart from the cough. We took him back in yesterday as he wasn't really picking up and they took him straight to hospital. They've just called to say he has a serious heart problem. They're going to try him on some drugs tonight and if he doesn't respond, I think that's it. If he does respond, he can go onto pills, but I think we are then talking about months or even weeks, and probably being quite ill. Don't know why I'm posting really - just wanting a bit of comfort. Also, any advice on how to support the DCs (6&8 - they adore him) through it would be helpful.
