"A review of 7 published studies and 1 anecdotal report involving dogs born in high-volume commercial breeding establishments and sold to the consumer directly via the Internet or indirectly through retail pet stores revealed an increased incidence of behavioral and emotional problems that cause distress in adulthood compared with dogs from other sources, especially noncommercial breeders."

Holding back the genes - limitations of research into canine behavioural genetics

ABSTRACT

"Canine behaviours that are both desirable and undesirable to owners have a demonstrable genetic component. Some behaviours are breed-specific, such as the livestock guarding by maremmas and flank sucking seen in Dobermanns. While the identification of genes responsible for common canine diseases is rapidly advancing, those genes underlying behaviours remain elusive. The challenges of accurately defining and measuring behavioural phenotypes remain an obstacle, and the use of variable phenotyping methods has prevented meta-analysis of behavioural studies. International standardised testing protocols and terminology in canine behavioural evaluations should facilitate selection against behavioural disorders in the modern dog and optimise breeding success and performance in working dogs. This review examines the common hurdles faced by researchers of behavioural genetics and the current state of knowledge."

• Early out walks

excerpt... Early out walks Veterinary behaviorists  are "FOR" and tell you why  

The owner who is considering or has just acquired a puppy wishes to put all the chances on his side to ensure good health. In this area, the veterinarian is his best interlocutor.

It is also crucial that the puppy becomes an pleasant adult, non-aggressive and able to adapt to family living conditions. For this the owner takes advice, sometimes before the acquisition, from the veterinarian who will follow his dog for several years.

The veterinarian must be able to position himself and be able to give good advices for the animal welfare and its integration into society as early as possible.
