COVID-19 - a novel experience for dogs and people

Sources of accurate and relevant COVID-19 information for your dog, your puppies and you. In the face of the great uncertainty surrounding COVID-19 and its impact on pets and pet owners, many veterinary and regulatory organizations have been providing excellent information and advice, as have kennel and breed organizations.  It is important to remember that recommendations and restrictions vary depending on location and owners need to access and follow local recommendations, especially as t

Epidemiology and clinical management of elbow joint disease in dogs under primary veterinary care in the UK & Effectiveness of Canine Hip Dysplasia and Elbow Dysplasia Improvement Programs in Six UK Pedigree Breeds

Epidemiology and clinical management of elbow joint disease in dogs under primary veterinary care in the UK excepts from the study... This study was conducted in the UK; it "shows that elbow joint disease is a relatively common diagnosis in dogs and has a high welfare impact. There are strong breed predispositions, in particular for large breed dogs." "The current study substantiated some previously reported breed-related variation in prevalence of elbow disease.

Linebreeding vs. Inbreeding – Let’s be perfectly clear. Note: This topic was prompted partly by IPFD's participation in the Canine Health Summit put on by Embark Veterinary. See our Q&A article on breeding and genetics topics here. Inbreeding is the mating of related individuals – that is those who have one or more relatives in common. Linebreeding is not simply a form of inbreeding – it IS inbreeding.   How close that inbreeding is depends on the selection of individuals with

Ask Aimee: Can my dog's ancestry test tell me who its parents are?

Recently we received a question from a Harmonization of Genetic Testing (HGTD) user, who had wanted to use an "Ancestry" genetic test to determine a puppy's likely sire. It is not uncommon, when trying to determine the right test for your purposes, to mistake "Ancestry" tests for parentage, or genetic identification tests. The information below talks about what ancestry, or breed mix genetic tests are, how they can be used, and some of the limitations. What is an Ancestry/Breed Mix Genetic

HGTD This week: How Breed Relevance Ratings (BRR) are estimated for cross-breeds and ALL dogs

Breed Relevance Ratings (BRR) are a way to assess the relevance of a specific test for a specific breed, based on the currently best-known information on the research and development of a test - but genetic tests are not limited to pedigree breeds. Genetic tests are used for a variety of reasons on all dogs, and understanding the relevance is important for any purpose-bred dog or breeding program, as well as individual dogs. BRR’s are estimated for all dogs, and where the research is not availab

Responsible Breeding and Sourcing of Dogs - Bonnett Swedish Vet Congress Oct 2020

I was honoured to participate - virtually - in the Swedish Veterinary Congress in October. This talk, as requested by the organizer looks primarily at the veterinarian's responsibility in issues related to responsible breeding, current legislative and regulatory actions, and various controversial issues in dog health and welfare - including extremes of conformation.  It also addresses concerns about how importing of dogs might impact the situation. Sweden historically has a population

German Shepherds - Research confirms the obvious??

According to a press release from the University of Surrey in the UK:  "Movement of German Shepherd Dogs is dependent on their shape".     Perhaps most people might first respond like I did, i.e. No Kidding! I do not think it takes an anatomist or veterinarian or experienced dog person to think that the dogs in these images might 'move differently' and that it likely would have something to do with their shape. But hey.  We all try to find catchy titles for press release

HGTD This Week: What does is mean when a dog is promoted as "genetically tested?"

19 Oct 2020 If you’re a dog owner, or looking for a puppy what does it REALLY mean when a dog is “genetically tested”? “My dog is genetically tested” is an increasingly common statement from dog owners. We see it on breeder’s webpages as part of advertising puppies, or as information on the dam/sire… it’s common on social media as a point of pride or a mark of care and responsibility by owners… but what does genetically tested (or DNA tested) actually mean? While using genetic testi

Calling All Breed Experts! HGTD’s phenes database and breed relevancy ratings (BRR) are an important source of information for anyone engaged in dog health and breeding, through the harmonizing of scientific data from a wide-variety of experts, research publications, veterinary and genetics researcher contributions, and in-house expertise.  Just as important, though, are the contributions from breed experts.

HGTD This Week, 7 Aug 2020: Canine Crime Scene Investigators

HGTD This Week, 7 Aug 2020: Canine Crime Scene Investigators When we think about genetic testing, we often focus on how it can be a tool to improve health and welfare - generally centered around breeding for health or finding more about the health or potential health risks for an individual dog. Knowing about health risks that are especially relevant to specific breeds or dog types makes testing even more powerful in helping reduce risks of disease or undesirable traits (see Breed Relevancy

HGTD This Week, 15 July 2020: One Disease, 20 Causes? It's All in the Name

The Harmonization of Genetic Testing for Dogs (HGTD) project work includes harmonizing genetic test information across many different boundaries. That can be as simple as adding consistency to nomenclature from around the world, or as challenging as cataloging test information and research from dozens of different international sources. With so much variation in how tests are developed, and how they are released to the public, a big part of my work is ensuring that phene names we publish on HGTD

The continued review of breed-specific tests for assigning relevance ratings, and ongoing discussions with genetic experts has led to a refinement of the breed relevance ratings (please see: BRR) . To better accommodate the spectrum of genetic test validation, we’ve added a new orange BRR.  The orange BRR indicates where all current available evidence has been reviewed, but the relevance is inconclusive. It could be that a mutation is detectable in a specific breed, but that there is no evi
