RE: The dog breed whippet can have a mutation in the genes that code for production of myostatin, resulting in the dogs having a huge muscle mass compared to other dogs from the same breed!
This is a very nice post and I don't want to interject a negative tone, but can't help noting that the bull seems to be in a body that can't be comfortable. I looked up a few things about Belgian Blues and see that in many instances they cannot reproduce naturally, but need repeated cesarean sections--also reproduction cycle is more rapid than usual, so they are subject to these operations frequently. Calves may suffer swollen tongues at birth and suffocate. It just doesn't seem to be an ethical proposition, perpetuating a mutation that will bring about such suffering. I know animal husbandry is a business and people eat meat. I just think we have a responsibility to obtain that meat in a way that brings the least amount of suffering to the food source.
I hope you forgive this serious interjection into your lovely blog about a dog. Dogs bring me joy and I liked looking at your pictures.
Don't feel bad about bringing this up, @agmoore. I totally agree with you, and it's far from ethical to raise Belgian Blue bulls for meat in my opinion. I do not endorse the use of this mutation for profit in any way, and I should probably have made that clearer in the post text itself.
I know you respect animals, so I'm not surprised :)
