Fluid around the heart

my border collie been diagnosed with fluid round the heart ha anyone else's fur baby ever had this she's maybe 14 years old but up until now she's been like a pup

Yes, my Lurcher Mia had this diagnosis, also at 14 years of age. She had the pericardium drained twice, but it was refilling over a 6 - 7 day period. She would then collapse due to the pressure on the heart muscle itself. My vet said the most common cause was a tumour in the heart muscle, and we decided we were not prepared to continue to have her drained at such frequent intervals.
It was a sad time for us as she seemed well enough between these procedures, but we couldn't keep subjecting her to so many GA's at that age. I'm sorry to not have a happier ending to relate, I do hope your girl turns out to have a different condition.

I'm sorry to hear about your situation. Hope you're vet find the best way to treat your dog.

never drained her give her 2 injections she's like a different dog today I would say 80% better

Good. I hope she continues to do well.
