Please think ahead! Way ahead. You have an animal that needs to have diagnostics run on 3 seperate tumors, biopsies, bloodwork, possible medications and surgeries. That is your responsibility and your Moms' . Your family agreed to care for her for her lifetime, including medical care. It is wonderful to dream, to think about the next great champion and hope it will be yours. After your obligations to the your current family are taken care of.
Be aware also that all show puppies don't win, some may not be able to show at all. Others may never be able to breed. I raised and showed Rotties for nearly 23 years. My mother raised Danes. We have had our hearts broken with pups more than once. Look at our show pup Goofy, she did amazing in her first 2 puppy entries, both 1st place! She then got such severe seperation anxiety that she would hurt herself in the crate if left alone, we hired a dog sitter, and that was just so we could go shopping. Her vet bills were enormous trying to find out if there was a medical cause. After long discussions and several months we decided to spay her (we paid all the breeders penalties) I moved my office from town to the house so she could be with me, reducing her need for tranquilizers. Goof will be a yr in November, not counting her purchase fee 1700.00 we have spent nearly 5,000.00 in vets, behaviorists and a yes a psychic. She is now a very expensive very loved PET! So yes dream and think and hope and save up , but take care of your first priority. Alaska.
