I posted about this exact concern a couple of weeks ago and the two responses were that "Chi's are already popular, so, therefore, the movie will have no effect."
I strongly disagree and would bet money that we will see a huge spike in the sale of this breed. Sadly, these dogs are NOT for everyone. Keep in mind that the movie will draw lots of kids begging mommy and daddy for "a cute puppy like that!" And mommy and daddy will oblige, cuz that's what a lot of people do (even though they can't afford other necessities in life, trust me, I've seen it and in the end the dog suffers....especially when the novelty wears off AND IT WILL) There is no question that this is one of the more popular breeds, but the intense attention that a movie like this will bring to the breed, will no doubt have the same effect that 101 Dalmations had on that breed (another dog that requires a certain type of owner who fully understands the personality and energy demands that they have).
But, there are lots of breeders, backyard or otherwise, who will and are probably already cranking out those puppies in anticipation of the strong demand for them. It's all about the $$, right....... UGH! I will NOT be seeing the movie and I pray to god that they never make a movie about my dog's breeds!!!
