Thanks for all the kind words gents. Really appreciated.
Labs really are the best dogs, our other dog is a pomeranian/lhaso apso cross - mainly a house dog - and whilst we love him to bits too, he just isn't as kind natured and easy going.
The vet we visit is pretty much an equine vet (she looks after my brother in laws dads horses) and even looks after farm animals, but has a small practice where she takes dogs and cats etc too. We reckon she's kind of matter of fact about animals and so maybe doesn't have as much sympathy toward pets? Clutching at straws here, either way not happy with how she went about things - especially on Tuesday night, she should have came out at half 9 and put him out of his pain, rather than him having to suffer a few ours and die of the tumour rupturing! I don't get their stance really, if we're paying then what's the problem?
No plans to get another big dog just yet. However, we've had a black and a white lab now so maybe a chocolate one is in order. It's hard with labs as they do end up with health problems, our last one was 10 and now Riley has died at only 8. Time will tell...
