DOG STAR RISING: THE CANINE GENETIC SYSTEM

THE CANINE GENETIC SYSTEM by Nathan B. Sutter and Elaine A. Ostrander Abstract: Purebred dogs are providing invaluable information about morphology, behaviour and complex diseases, both of themselves and humans, by supplying tractable populations in which to map genes that control those processes. The diversification of dog breeds has led to the development of breeds… Read More »

DO LARGE DOGS DIE YOUNG?

DO LARGE DOGS DIE YOUNG? Size and longevity in dogs by Frietson Galis1, Inke van der Sluijs1, Tom J. M. Van Dooren1, Johan A. J. Metz1,2, Marc Nussbaumer Abstract: In most animal taxa longevity increases with body size across species, as predicted by the oxidative stress theory of aging. Contrastingly, in within-species comparisons of mammals… Read More »

Evidence of inbreeding depression – by Professor Sonia Garzia

Evidence of inbreeding depression – a prospective study in the population of the European Dobermann – by Professor Sonia Garzia (2011) Introduction: Modern purebred dogs are plagued by many kinds of heritable diseases. The high prevalence of diseases and defects in pure dog breeds are due to high selection intensities in genetically closed populations (Ubbink… Read More »

Single-Nucleotide-Polymorphism – by Professor Paul Jones

Single-Nucleotide-Polymorphism Based Association Mapping of Dog Stereotypes by Paul Jones – Kevin Chase – Alan Martin – Pluis Davern – Elaine A. Ostrander – Karl G. Lark ABSTRACT Phenotypic stereotypes are traits, often polygenic, that have been stringently selected to conform to specific criteria. In dogs, Canis familiaris, stereotypes result from breed standards set for… Read More »

Average onset of DCM – by Bitten Jönsson

Average onset of DCM by Bitten Jönsson (2013) In our breed females starts to develop DCM around the age of 8 years …. A quite interesting statement, especially when the average lifespan in females diagnosed with heart problem/DCM is approx. 7,14 years. In addition to this, from diagnose and with appropriate medication, the average lifespan… Read More »
