Does breeding dogs fall under right livelihood? Does breeding and selling dogs fit into right livelihood provided that you make a concerted effort to make sure the animals find homes with responsible owners?



Edit:

Thanks for the answers so far. I am especially interested in answers that are rooted in the Pali Canon.

There are two relevant suttas that I found:


The Vanijja Sutta
The Dighajanu (Vyagghapajja) Sutta


However, it seems like there is dispute about how to translate and understand the relevant passages. Any answers that specifically address these issues would be appreciated.
Depends on which system your in. In the Mahayana system, the precepts have an animal liberation theme, i.e. not using animals for anything.

In the Upasaka precepts.


  (15) If an upāsaka who has accepted this precept raises cats or
  foxes, he has committed the sin of negligence. ...
     (16) If an upāsaka who has accepted this precept raises animals,
  such as elephants, horses, cows, goats, camels, or donkeys, and
  refuses to give them away to someone who has not received the
  [upāsaka] precepts, he has committed the sin of negligence. Without
  rising above this impure act, which is conducive to continuing his
  cyclic existence, ... he cannot avoid going down an evil
  life-path.

And in the Brahma Net Sutra precepts


  
  On Harming Sentient Beings
  
  
  A disciple of the Buddha must not sell knives, clubs, bows, arrows, other life-taking devices, nor keep altered scales or
  measuring devices.  He should not abuse his governmental position to
  confiscate people's possessions, nor should he, with malice at heart,
  restrain or imprison others or sabotage their success.  (82) In
  addition, he should not raise cats, dogs, foxes, pigs, and other such
  animals.  (83) If he intentionally does such things, he commits a
  secondary offense.

I'm a vegetarian myself, and sympathetic to animal right issues-- the pet trade, zoos, and circuses do involve a certain amount of unneeded suffering and death on the animals parts, but for some people, their dog or cat is the only reason they have any sympathy at all for non-humans. So pets are a sort of unvolunteered diplomats for their species and animals in general.

Anyhow, here is one asian, dog charity I follow- https://www.facebook.com/pages/Duo-Duo-Animal-Welfare-Project-%E5%A4%9A%E5%A4%9A/380841222033262
