So would you say that if a breeder said that their puppies are not heart tested because this only verifies that they do not have a heart murmur present and didn't really respond when asked about the parents health tests that this would be something to be concerned about?
Thanks again.
As an example... here are the test results we got from our breeder when we asked for them.
Parent 1 (name withheld in accordance with board rules)
ARVC: Positive Heterozygous
SAS: Clear
Echo Doppler: 1.6 flow rate.
OFA #: BX-CA1879/16M/C-VPI-ECHO.
Holter : 3/12/11 0 VPC's
Clear of CHD: PennHip .48 DI, no cavitation or degenerative joint disease either hip.
DM: At Risk
Parent 2 (name with held in accordance to board rules)
ARVC: Positive Heterozygous
SAS: Clear
Echo Doppler: 1.85 flow rate
OFA #: BX-CA2217/49F/C-NOPI-ECHO.
Holter: 2/24/12 2 VPC's
Thyroid: Normal
DM: Carrier
Now, looking at ours, the Positive heterozygous in both parents meant that the pups would have a 25% chance of being positive homozygous for boxer cardio myopathy, which by the way our pup has but we know that going into the purchase.
To help you out... the ARVC is testing genetic markers to see the risk of passing on the predisposing for boxer cardio myopathy.
SAS is testing for Stenosis, which is another common heart issue in boxers
Echo Doppler is another heart test that shows the beat and blood flow of the heart.
The OFA# I think is testing for hip/elbow dysplasia... maybe someone with more knowledge could expand on that.
Holter is a 24 hr EKG to test the heart for irregular heart beats that could show boxer cardiomyopathy
The Thyroid test is obviously testing the thyroid
The DM screening is a genetic test looking at the markers for Degenerative Myelopathy. There are very few boxers that have a test result of clear DM, so an at risk with carrier is considered ok for breeding.
What we looked for in a breeder when we purchased our little girl:
1. Actively showed dogs. IE, they were breeding to get their next champion, not to make $$$$ as a business.
2. Goes along with #1, How often did they have litters? IE, if they were just churning out litter after litter that could be a warning of not taking all the steps needed to product responsible.
3. Did NOT own both the breeding parents. IE, they were looking for the best match for the litter and not just what they had on hand.
4. Did health testing on both parents and offered those results to us prior to purchase.
5. Offered a health warranty
6. The last and final consideration was cost...
Hope this helps.
