So sad!
Accidents can happen to anyone, even the most responsible, and I’ve sometimes not microchipped mine til that age, waiting for a clinic, etc.
Who knows if this represents a responsible bloodline that is especially worthy, health-tested, temperament and conformationally and pedigree wise expected to have much worthy to contribute to future generations, all lost now because of this precipitous action?
The good thing, (if there is one), is that Labs at least have a large enough gene pool that the loss of one breeding animal, no matter how desirable, is probably not going to have a significant effect, breed-wide, though it may represent a real loss to the owners.
In a breed with a very small gene pool, it could potentially really damage the potential population of worthy animals.
Regardless, it could adversely affect the health of that particular animal, as recent studies have shown, increasing the chances for osteosarcoma and a whole list of other conditions (though research also shows the results of neutering at this age would be worse if it were a Golden as compared to a Lab).
I am glad the dog was found, and hope the original owner will be found and deals with whatever the neutering entails, emotionally. They will be so ahppy to be re-united, I would imagine it might take awhile to process. Failing that, I hope he finds a great home and that he will be spared any adverse impacts on his health in the future.
I too am so taken aback that someone would do this!
