“…Furthermore, unsocialized puppies outperform wolf pups in following human communicative cues (Hare et al ). Additionally, Udell et al () found breed group differences in the performance of dogs on a human‐guided task, again suggesting a significant genetic basis for social skills in dogs. Considering all of these findings together, the outstanding social skills of dogs are most likely a result of domestication and selective breeding, but can be shaped further by individual experiences.…”

“…This is further supported by the observation that foxes selected for tameness perform as well as dogs and significantly better than control foxes in similar tasks (Hare et al ). Additionally, breed differences have been reported in the ability to follow human communicative cues (Passalacqua et al ; Udell et al ; Wobber et al ). All these results suggest that social skills in dogs are the direct result of domestication, probably have a genetic basis and have been selected for and further enhanced in some breeds.…”

Through domestication and co-evolution with humans, dogs have developed abilities to attract human attention, e.g. in a manner of seeking assistance when faced with a problem solving task. The aims of this study were to investigate within breed variation in human-directed contact seeking in dogs and to estimate its genetic basis. To do this, 498 research beagles, bred and kept under standardized conditions, were tested in an unsolvable problem task. Contact seeking behaviours recorded included both eye contact and physical interactions. Behavioural data was summarized through a principal component analysis, resulting in four components: test interactions, social interactions, eye contact and physical contact. Females scored significantly higher on social interactions and physical contact and age had an effect on eye contact scores. Narrow sense heritabilities (h 2 ) of the two largest components were estimated at 0.32 and 0.23 but were not significant for the last two components. These results show that within the studied dog population, behavioural variation in human-directed social behaviours was sex dependent and that the utilization of eye contact seeking increased with age and experience. Hence, heritability estimates indicate a significant genetic contribution to the variation found in human-directed social interactions, suggesting that social skills in dogs have a genetic basis, but can also be shaped and enhanced through individual experiences. This research gives the opportunity to further investigate the genetics behind dogs' social skills, which could also play a significant part into research on human social disorders such as autism.

“…Unfortunately, the main criterion often relates to a matter of availability (Mehrkam and Wynne, 2014). More recently and for the first time, Udell et al, (2014) have compared working breeds with a specific selection pressure during domestication and have demonstrated that breed-specific predatory motor patterns can serve as an important predictor of success in an object-choice task. Furthermore, the empirical evidence of breed differences in non-social cognition is scanty.…”

“…During domestication, hunting ability could have been considered among the most appreciated traits to select for; evidences have been found that 4000 years ago in the Middle East and North Africa, selective breeding for hunting aptitude was applied [23,24]. The typical hunting behavior of pointing breeds is represented by an interruption of the natural wolf predatory sequence, stopping in front of their prey [25,26]. Furthermore, the introduction of firearms in hunting drove a double goal in dogs' performance ability: both pointing the pray and keeping away from the rifle [24].…”

Simple Summary: In order to protect domestic animals' biodiversity, a deep knowledge of the genomic makeup is required. The authors describe the genomic architecture of the German Short Hair Pointer breed and analyze the inbreeding levels under a genomic and a genealogic perspective. Twenty-four dogs from Italy were genotyped and analyzed jointly with 10 dogs from USA, whose genotypes were available from a published research. The authors investigated the genomic structural variation of the breed using runs of homozygosity-the direct measurement of the proportion of homozygous DNA, i.e., genomic inbreeding. Some traits clearly revealed the selection objectives addressed in the breed. The results describe a low inbred population with quite good levels of genetic variability.Abstract: The German Shorthaired Pointer (GSHP) is a breed worldwide known for its hunting versatility. Dogs of this breed are appreciated as valuable companions, effective trackers, field trailers and obedience athletes. The aim of the present work is to describe the genomic architecture of the GSHP breed and to analyze inbreeding levels under a genomic and a genealogic perspective. A total of 34 samples were collected (24 Italian, 10 USA), and the genomic and pedigree coefficients of inbreeding have been calculated. A total of 3183 runs of homozygosity (ROH) across all 34 dogs have been identified. The minimum and maximum number of Single Nucleotide Polymorphisms (SNPs) defining all ROH are 40 and 3060. The mean number of ROH for the sample was 93.6. ROH were found on all chromosomes. A total of 854 SNPs (TOP_SNPs) defined 11 ROH island regions (TOP_ROH), in which some gene already associated with behavioral and morphological canine traits was annotated. The proportion of averaged observed homozygotes estimated on total number of SNPs was 0.70. The genomic inbreeding coefficient based on ROH was 0.17. The mean inbreeding based on genealogical information resulted 0.023. The results describe a low inbred population with quite a good level of genetic variability.
