Colours in Havanese & health of breed
Was just doing some reading on colour restrictions in other dog breeds, particularly Boston terriers. Sounds like many perfectly healthy dogs are removed from breeding lines as they are not the specific correct colouration listed in the breed standard. I'm all for breed standards but in some cases it sounds like the same genes produce these different colour patterns so good dogs are being removed from the breed for somewhat arbitrary reasons, especially when the colours were acceptable at one point in the breed's history. Of course that would tend to shrink the gene pool, and potentially amplify out other health problems. Seems like something really important with any breed is to have a diverse and healthy gene pool.
It got me to thinking that we're quite fortunate that the many different colours of Havanese are acceptable in the show ring. With the small gene pool the breed has started with, at least in the U.S., it would likely only make things worse to be breeding for very specific colours any more than is already done. Of course there are some colouration requirements with regards to eye rims, nose, etc, but overall we are not taking perfectly healthy dogs out of the breed for lack of a correct pattern/colouration. Lucky us, and we get to have all these cool looking little dogs of all kinds of interesting patterns and colours prevalent in our breed!
Anyway just some food for thought/discussion if anyone else is into this kind of stuff. I'm only a newbie when it comes to dog genetics and breed standards so please correct me if I'm making any incorrect assumptions!
