Potential Health Problems in Doodles and Why Choosing a Breeder Carefully is Critical.
Hybrid Vigor?
Some of you may have read claims that mixed breed dogs are "healthier" than pure breeds because of "hybrid vigor" that results when two different breeds (and their greater genetic variance) are combined. However, I've seen this "hybrid vigor" idea abused by those who want freedom to throw any breeds together and call it "healthier." The truth is that any potential "hybrid vigor" is merely a potential benefit, not a guaranteed benefit of buying/adopting a mixed breed dog.
As many of you know, many diseases and health problems are hereditary. That means it doesn't matter WHAT the breed or mix is...if one or both parents carries a genetic problem that can be passed down, the offspring may also end up either carrying that disease in their genes or actually developing that disease.
Because of this possibility it is vitally important to do your homework before choosing a breeder. If you are in the market for a doodle (or any other breed or mix) study the individual breeds in the mix and find out what their health weaknesses are. Then...make certain that the breeder you choose tests for the testable diseases common in those breeds.
It's not enough that two breeding dogs seem to be healthy and so far have been the picture of health. It's not enough that a breeding dog goes to the vet every year and gets a stamp of "health" from the vet. Many diseases and genetic predispositions are not visible to the naked eye and without specific health testing there's no way to know if there is a problem.
So what are common hereditary diseases in labs, goldens and poodles & the tests needed to screen for those problems?
* Canine Hip Dysplasia (CHD) is either a malformation of the hip joint or looseness of the hip joint. Either way it can be a pretty debilitating issue causing pain and difficulty walking/playing/etc and it is common in all three breeds. However, this is a multi-factorial disease--meaning it's not caused just by one thing or one genetic defect and the result isn't just one problem. Right now there are two main tests a good breeder may use to determine their dogs' hip quality: The most common test is an x-ray done through the Orthopedic Foundation for Animals so the test is often referred to as OFA. It's not the OFA that does the actual test, they just read the results and issue a rating/clearance. The test rates the formation of the hips. Hips that are rated Fair, Good, or Excellent are considered "passing."
The other test for hips was created by University of Pennsylvania and is called the PennHIP -- PennHip does not give a "clearance" but grades the dog's likelihood of developing CHD using a distraction index (DI) that measures hip tightness or looseness. Scores received from PennHip are numbers under 1 such as 0.55 or 0.70, etc. This grading shows how a dog's hips compare with others in their breed. A score like 0.50 shows that a dog's hips are at the 50% percentile or equal to about the "average" hips for that breed. The higher the numbers mean a lower percentile. The lower the number, the higher the percentile which means tighter hips.
It is very important that you choose a breeder that does either or both of these hip tests (especially for medium and standard size doodles) to minimize the chances that your pup will develop CHD. But do keep in mind that although starting with healthy hips will reduce your risk of problems, it won't guarantee it.
* Elbow Dysplasia, Patellar Luxation, and Legg-Calve-Perthes Disease are also conditions that OFA deals with and many breeders test for. However, I'll leave the reading on this up to you--info available on the OFA site.
* Eye disorders Each breed has the potential to carry/have various eye disorders. I won't go into each one, but to minimize your risk look for a breeder that does CERF testing and/or PRA testing. CERF stands for Canine Eye Registration Foundation. A certified ophthalmologist must examine a dog's eyes for this test (not just any vet). PRA stands for Progressive Retinal Atrophy and is a genetic disease of the retina which eventually causes blindness. A CERF exam can see evidence of PRA, as well as other eye problems. But the PRA test is a DNA test to ensure that a dog is free of the gene so that it does not get passed on.
* Canine Von Willebrands disease also known as vWD is a bleeding disorder similar to hemophilia in humans and is more common in poodles than in labs or goldens...but since a doodle is part poodle it's an important test to ask about when choosing a breeder. The tests most breeders use a DNA test that shows if a dog is either affected or a carrier or clear of the disease. An affected dog would/should never be bred.
The list of testing above is not exhaustive nor does it prove a breeder's quality. However, it's a place to start and from there your screening of a breeder should include telephone and email conversations as well as a visit to the premises when possible (breeders also need to be able to keep their breeding grounds safe and sanitary for their puppies and allowing daily visitors is not always safe). Look for a good health guarantee and read the health guarantee contract as if you already have bought the pup and it's now a year old. If your 1 year old develops hip dysplasia...would you be happy if the contract required you to return this dog you love? Or would you want some other kind of compensation?
As you can now see, the health of a puppy is not determined merely by being the offspring of two different breeds, but by being the offspring of two healthy dogs (regardless of breed) with a good background, bred by a breeder who stays up to date on health issues of the breeds in question. These are just my thoughts, I welcome discussion if I got any facts wrong. Always do your own homework/research before choosing a breeder.

So, so true! Thanks so much for posting this. Health testing is vital. Bravo to all the breeders who do all the necessary testing!

Wow. Hopefully my Kachi will be ok. He's 7 1/2 months old, already weighs 47 lbs, and he loves going up and down the stairs. We also walk at least an hour per day, and then he goes to puppy play group 2x a week where he runs himself out!! He also jumps up and down off the couch many times a day (and occasionally from one couch to the other, when he thinks no one is looking) And unfortunately, he has slid on the kitchen tile more than once, chasing his tennis ball. But, he is really sturdy, very muscular, and solid, and I would think strong muscles would be a plus to a growing dog, and even a necessity, for helping to prevent injuries. Can an x-ray of a puppy's hips taken now, show the potential for trouble down the road?

We have stairs that lead to our backyard...just 2-3 stairs but Rosco took a few flying leaps off of those...I wasn't as vigilant cuz Rosco weighed 30 lbs at 12 weeks.

I can absolutely vouch for that Annmarie, I aquired my beautiful dog Finny through Ann.
Regarding strenuous exercise, we originally toyed with doing all sorts of things with Finn; TV work, therapy work and agility. In the end we decided we didn't want Finn to be a 'working dog'. (I know they don't see it like that!) We walk Finn for at least an hour a day, often on the North Shore Trails, where he scampers up and down banks and does little jumps - and then we often go to the park in the evening as well to play Flicker-ball. He belts after that! He's only 1 year old. Could I be exercising him a little too much!?

Yes, I'm sure you can speed up the process of hip issues. But I don't imagine a pair of excellent hips could get damaged bad enough to lead to HD just from puppy jumping or running too hard on its own -- it's JUST a guess though, who knows. But other things could get damaged anyway so best to take it easy as you say.

We wanted to give this extra year because of things like hip dysplacia which can be such a problem for the owners with vet expenses that can mount up high if diagnosed. But it will cover any major congenital disease that may pop up in that time. We cant control health but if a dog is healthy before it is born and maintains a good diet health issues should not pop up in the first 3 years.
We feed the mom a super healthy diet before pregnancy begins with real meat , chicken beef, lamp, veggies, eggs, flax seed and continue this super enriched diet after pups are born to ensure a super milk supply to feed all her pups. They all have access to dry kibble (CANADAE) also to nibble on. Kelsey could eat and eat especially when pregnant , so she is really pampered throughout the entire period of time.
She has had some large litters and was able to maintain all their weight gains on breast milk alone until this last litter in which she had 3 that were super small , weighing only 3 oz a piece, so we assisted her by supplementing their diets with formula for a few weeks.

That's great that you offer a 3 year health guarantee! Since most dogs don't develop some things until after 2 years ... 3 years is really cool. What health conditions does it cover?

Our first Labradoodle "Killean" came from a kennel / puppy mill broker really. It was a horrible experience. & days after bringing our baby home he came down with Parvo. A virus that will and can cause death upon puppies. We had to return him in order for us to get our $$$ back. It was a horrible experience Tom & I never want anyone else to encounter, and that is our Main reason for breeding Labradoodles ourselves , to ensure for 3 years of health on all of our puppies or a full return on their money without having to return their dog to us. Any warrentee with the words MUST return dog in order to get your $$ refunded stay away from.
Stay away from any store that sells puppies. They feed and allow "PUPPY MILLS" to prosper. Educate yourselves on this breed and go to a private breeder, where the sires and dams are a part of the family not in kennels.(fist clue) on puppy mill.
Visit the breeders home, ask questions, meet the parents of the puppies. Within 10 mins you will know if they are right for you.
