The vet in that practice - who was our vet prior to my daughter working there - states the same based on his 30 years of practice.
I find it irresponsible that you would broad-brush rescue dogs in such a cavalier manner. You can get health and temperment issues from purebread dogs, as well. Either way, it's a crapshoot. With a rescue dog you do have an opportunity to get to know the animal and observe his/her health providing you're working with a responsible rescue organization.
Many times you bring home a purebred puppy that has been delivered from a puppy-farm mother and you don't have a clue as to the problems you've purchased until months later when they appear. I have a neighbor who purchased a purebred and it was 6 months before they learned it had an immune system disorder which has the animal in constant pain, requires daily medication, and has cost them several thousand dollars at this point. The dog is not yet a year old. I know this because my daughter dog sits for them. They need someone with vet skills who can give the medicines if they go out of town.
My dogs are neutered and spayed and I would recommend that everyone do so. I've not seen - but have not looked for - evidence that doing such shortens their lifespan but it's one of those risks we'll have to take. Puppy birthing is not without its own risks so it's a trade-off for her.
I'm sure you hope your purebred will outlive my mixed breed but you truly have no clue. Maybe we should get back to each other in a few years to compare notes? As far as quality of life - other than health, the quality is purely subjective.
BACK TO THE ORIGINAL POSTER - Find a good humane society in your region. They usually have open houses, special events, etc., where you can go in and see how they operate. They should have a full history of each animal, including where they got it from and the circumstances. They do NOT want to pass on animals with problems as they don't wish to be held responsible and they don't want the dog coming back to them via an unhappy adoption.

On the negative side, neutering male dogs:
• if done before 1 year of age, significantly increases the risk of osteosarcoma (bone cancer); this is a
common cancer in medium/large and larger breeds with a poor prognosis.
• increases the risk of cardiac hemangiosarcoma by a factor of 1.6
• triples the risk of hypothyroidism
• increases the risk of progressive geriatric cognitive impairment
• triples the risk of obesity, a common health problem in dogs with many associated health problems
• quadruples the small risk (<0.6%) of prostate cancer
• doubles the small risk (<1%) of urinary tract cancers
• increases the risk of orthopedic disorders
• increases the risk of adverse reactions to vaccinations
On the negative side, spaying female dogs:
• if done before 1 year of age, significantly increases the risk of osteosarcoma (bone cancer); this is a
common cancer in larger breeds with a poor prognosis
• increases the risk of splenic hemangiosarcoma by a factor of 2.2 and cardiac hemangiosarcoma by
a factor of >5; this is a common cancer and major cause of death in some breeds
• Triples the risk of hypothyroidism
• increases the risk of obesity by a factor of 1.6-2, a common health problem in dogs with many
associated health problems
• causes urinary “spay incontinence” in 4-20% of female dogs
• increases the risk of persistent or recurring urinary tract infections by a factor of 3-4
• increases the risk of recessed vulva, vaginal dermatitis, and vaginitis, especially for female dogs
spayed before puberty
• doubles the small risk (<1%) of urinary tract tumors
• increases the risk of orthopedic disorders
• increases the risk of adverse reactions to vaccinations

Read the entire study and THEN talk to your Vet about it... I did.
My breeder has been a Vet for longer than I have been alive by the way...
FWIW - The last time I got into this debate with a Vet and we started sharing studies on the matter (no shouting - just facts and studies to prove our points) The ONLY studies she could provide to back up her case/claims were 30 to 40 years old...
