I know two people with them, one of them is pretty healthy, slobbers tremendously, and has only had a couple of ear infections in the 4 years he's been around.
The other one is a disaster. He has constant ear and eye infections, has a bad shoulder, and skin problems too, probably allergies.
Funny thing is, the good one cost nothing, it was in a newspaper ad, and the sick one was 750 dollars and was from a good, well known breeder.
I prefer Mutts myself. My last dog, a Pit Bull/Golden Retriever/??? mix, was a freebie, and except for a major injury to his neck, was very healthy until we had to put him down when he was 14.5 years old.
My present dogs are littlermates, Lab/Doberman/Husky? mixes, and the male has had a couple of ear infections, and a skunk bite got all infected once, and that's about it. The other one, his sister, has major allergies, and scratches herself constantly, as soon as the heat gets turned on, until May or so, when it gets turned off. She has at least one bad hip too.
My sickest dog?? My Yellow Lab that I paid 300 bucks for (nearly 30 years ago), from a good breeder, who turned out to have the following problems:
Rheumtoid arthritis
Too small an opening for his johnson (really!) More common than you might think.
And on top of that, he was a hermaphodite! One testicle, and one ovary. He gained 20 pounds when the ovary was removed and looked like he was on roids!
He had illness after illness. Strokes, pancreatitis, congestive heart failure, and more.
He went senile/crazy one day, after doing better than he had for some time, and attacked the 20 pound lighter Pit mix. Not a smart move. I had to rescue him, the other dog, that worshipped him, had been pushed too far, and it was no contest. He went sour amazingly fast after that, and we had to put him down the next day.
After the Pit mix went, I was planningon waiting and getting two littermate Greater Swiss Mountain Dogs (Kind of a more mellow Rottweiler relative) about 6 months later. Well, a friend's GF had 13 pups to get homes for, so we went and looked, and brought two home.
