just do your homework, aussies can have alot of health problems, WEIRD ones , been there done that.
Also ask the breeder if she's had her dogs MDR1 gene tested. It's a sensitivity gene and IF they carry it, depending on the level, normal doses of certain drugs can literally kill them. IF she's unaware of this MDR1 thing, then Id say she isn't as informed about aussies as she should be.
Another kennel who's dogs I like, and I think are in TX, not sure tho, is Slydrock, I also just saw a posting for a kennel in louisiana, hammond to be exact, and I would "kill" for this puppy they have available is "Goldring" Australian Shepherds, I've gon thru this website (goldring) and she is definately someone I would buy a dog from. Her dogs are very versatile and she sounds like she knows her stuff.
