Hi my name is Annette. I am new to this breed and learning all I can. Please help me in my education before I purchase my first dog. I have a horse boarding and training stable. I have 3 chihuahuas. Small rat terrier and a 60lb mixed herding dog. I'm looking for a companion dog to take jogging, to take to out of town horse shows and a companion on the ranch, because I work with horses here on the ranch everyday the dog would be with me pretty much 24/7. Here are some questions I have. What have you found in the pros/ and cons between males/females. How does one find a good vet for cropping ears? What is the going rate for cropped ears? Are there any issues due to health with any certain colors? In the horse world white and light grey colors tend to be more cancer prone. Please send me any links to good breeders. Thanks
