Labs like a number of other breeds are extremely prone to hip dysplasia - which is a VERY expensive condition to correct and there are no 100% guarantees even from reputable breeders.

The saluki/desert dogs one can find often at QAWS are loyal, smart, trainable, and can cope with conditions here in Qatar much more easily than the Lab. Labs were bred for Canadian climates (think cold!) not desert conditions. They remain "babies" mentally for about 3 years if not longer. They are "mouthy" meaning that anything they come in contact with ends up in their mouth at some point - they're bred to pick up things so that's what they do - a lot of people don't understand it's a natural thing for the dog and don't like the behavior.

Do a LOT of research and talk to lab owners BEFORE you take this breed on. Are they worth the huge amount of work and effort? Yes. Are you willing to put that work and effort into the dog? Only you can answer that question.

BTW Labs average about 10 - 12 years in life span - are you in a position to look after the dog for that long (vet bills, vaccinations, kenneling when you go on vacation, 2x 45 minute walks minimum per day, training, etc.)
