My dad and I had Brittany's for about 20 years, a long time ago I had one expecting pups that went limp and energy less overnight, the pups were delivered emergency C section and with other treatments the bill was near $500 dollars I think. That dog was a hellacious hunter, I would have loved for her to have survived but she died on the table. A few years later another female I had had problems at birth and had a reaction to the anesthesia and didn't make it. She was just as much a hunter than the other.
One of my dogs a year ago in November, who was the lone survivor of a litter of eight from my first Brittany I lost, we think died of kidney failure. He died in my arms at the vets office trying to figure out what was going on with him.
My oldest Brittany I had to have put down just after Christmas last year at 15 1/2 years old. At one time I had been offered $7000 for him but declined it and hunted the heck out of him for the next 10+ years. That one was probably my cheapest in overall vet bills as he only required stitches a couple times (sheared metal T posts can make for a heck of a slitting item when they are about 6" tall.. found in an old fence row while hunting one day), feed and shots/vaccinations/worm medications.
But the lifetime of memories I have with those dogs was priceless. That being said I don't know what amount I would have said no to on my oldest living one.
Now I have horses, two to be exact. One is a 20 year old gelding 'Whisper', the other is a 23 year old mare 'Tonka'. My 7 year old daughter and Tonka are best buds, I hope when its Tonka's time she goes quick and isn't a long drawn out affair. I also wish that I had that horse about 7 or 8 years ago when I had awesome birddogs, I think my team of horses and my birddogs would have worked in the field well together.
