Why buy a 'proper' Fox Terrier?
To sum up, it costs as much to feed and care for a real Foxy as it does a mongrel. Veterinary charges will be the same for both. It is also a fallacy that pedigreed dogs are more sickly than mongrels - in fact, if bred correctly from sound parents and ancestors, they are usually much healthier and Fox Terriers, in particular, are known by vets to be really hardy and resilient. If you purchase a puppy from a reputable breeder and view either one or both parents, you know what you are getting because it is all printed out on the KUSA Certificate of Registration and the Breeder's Pedigree.
