I guess it depends on what you consider alot.
I used to have 2 Rotties. They shed a lot more than the chis. But I tend to brush/comb the chis more.
And I have 4 cats so the only hair I see around my house is cat hair.
Oh, I have 2 long coat chis.
I own three Chihuahuas. Two are short coats and one is long-coated. My shortcoats SHED LIKE CRAZY!! "Bruiser" is white and he leaves hair on everything! You can not wear anything black and pick him up! He has a very healthy coat of hair, but man does he shed!!
mine is short hair and she sheds a good amount even though i brush her every other day. plus she is white so i need like a lint roller when i wear black! i have a samoyed too (sort of a husky type dog) so compared to her the chi is no problem at all
I only have Gadget and he is 9 1/2 weeks old and I haven't seen any shedding yet... We are not sure if he is short or long coat yet, but We think he is going to be long... His mom and Dad are short coats and they shed like crazy.
