Companion Dog Registry 

CDR registers mixed and purebred dogs who meet health and temperament criteria, and the puppies from approved breedings of registered dogs.


A CDR registered puppy is always an excellent choice. Not because of its purity or a guarantee it will be the perfect dog, but because you know it came from a professional, knowledgeable breeder, its parents live great lives, and it was given the very best possible start in life.


CDR registered puppy owners have the unique opportunity to participate in data collection about their puppy as it grows, helping to insure that the puppies of the future be even healthier, happier companions.


Read about requirements for registration below.

CDR Registration Requirements 

Only CDP member breeders are eligible to register dogs

Requirements to register an adult dog (also applies to converting a puppy registration to adult ) 

Individual support to applicants including guidance about health testing requirements is available

. Temperament:


  • Bite history: Dogs with any human bite history are not eligible. Dogs with a known Dunbar scale level 3 bite  history in a sibling or parent are not eligible. Dogs with history of bites on other dogs requiring veterinary care may be considered on a case by case basis.  


  • Resource Guarding: No history of aggression toward humans when in possession of a toy or food item. Tolerates other known dogs in the household without biting or excessive guarding. 


  • Tolerance of examination: able  to undergo veterinary examination and routine preventive care without the need for  sedatives, behavioral medications, or excessive restraint  


  • Response to new environments: Able to remain composed while  walking on a leash in unfamiliar public areas where it encounters unknown dogs and humans without excessive guidance from the handler. Ideally this is achieved without formal training or conditioning. 


  • Response to new humans in familiar environment: Tolerates unfamiliar visitors to its home environment without an aggressive response and preferably a pro social response. Ideally this is the case with minimal to  no training having been provided.

  • Response to new dogs in familiar environment: Tolerates unfamiliar dog visitors to its home environment without an excessive aggressive response and preferably a pro social response.


  • Separation: Over 6 months of age, is able to tolerate being alone for up to four hours without harming itself through attempts to escape, compulsive behaviors or soiling. 


  • Unacceptable Behaviors: any submissive urination or consistent excited urination past 6 months of age, compulsive behaviors such as licking, spinning, fixation on environmental stimuli, persistent attempts to escape confinement despite adequate exercise and stimulation, inability  to be reliably house trained by 6 months of age, prey drive that if unmanaged could reasonably be expected to result  in the injuring of a domesticated cat or dog, human or dog aggression, resource guarding toward humans. 


2. Health: 


  • Has never been diagnosed with any condition that significantly affects quality of life or requires costly, repeated, or painful veterinary intervention for which a genetic basis is established. 


  • Appropriate DNA testing based on breed content.


  • Additional health testing requirements will be determined for each individual applicant based on breed content and size.

Most dogs will require:

  • Hips (PennHip preferred)  (excellent or good OFA prelims over one year old are acceptable) 

  • Elbows (normal prelims over one year old are acceptable)

  • Cardiac - advanced cardiac (echo) over one year old is acceptable and preferred. Without an echo, OFA basic within one year prior to breeding. 

  • Eyes (CAER over one year old is acceptable) 

Additional required tests based on breed content may include:

  • Patellas

  • Thyroid

  • MRI

  • Spinal X-rays 


4. Structure:

Submission of side view photo, and photo of head required. Extremes of conformation or brachycephaly may be considered as part of a program to improve health and function. 


5. Family history:

Documentation of breed content as revealed by Embark testing and/or pedigree. Dogs with significant breed content that is traditionally not consistent with the goals of the breeding strategy may require additional documentation of temperament or be declined. Dogs with wolf content will not be considered. 

Requirements to register a litter:


  • Sire and Dam must be CDR registered as adults (studs not owned by members can be used without registration if all requirements are met) 

  • Puppies will be microchipped with a chip permanently linked to either the breeder or the CDR prior to leaving the breeders possession. FiNano chips are included with litter registration at no extra cost. 

  • First time pairings require documentation of predicted genetic COI of 10% or less. Mixes with known pedigree and no breed overlap (F1 or equivalent) may be assumed to have COI <10%

  • Past litters may be registered up to 5 years after date of whelp assuming all requirements are met

  • Females should be bred no earlier than second heat AND over 18 months. Dogs with unknown parentage  must be fully socially mature (2-3 years old) to establish adult temperament prior to breeding. 

  •  Skipping heat cycles is optional and should be based on veterinarian recommendation, breeding goals, and the condition of the dog. No female may be bred more than 4  times or after age 8 without prior examination and approval of a licensed veterinarian 

  • Dogs should be in overall good health at the time of breeding with normal appetite and having no sign of illness, in healthy body condition, with good mobility of all joints, at a healthy weight, parasite free and up up to date on vaccines as recommended by a licensed veterinarian
