Noninvasive sampling of the small intestinal chyme for microbiome, metabolome and antimicrobial resistance genes in dogs, a proof of concept

Background The gastrointestinal microbiome and metabolome vary greatly throughout the different segments of the gastrointestinal tract, however current knowledge of gastrointestinal microbiome and metabolome in health and disease is limited to fecal samples due to ease of sampling. The engineered...

Examining dog–human play: The characteristics, affect, and vocalizations of a unique interspecific interaction

Despite the growing interest in research on the interaction between humans and dogs, only a very few research projects focus on the routines between dogs and their owners. In this study, we investigated one such routine: dog–human play. Dyadic interspecific...

Investigating emotional contagion in dogs (Canis familiaris) to emotional sounds of humans and conspecifics

Emotional contagion, a basic component of empathy defined as emotional state-matching between individuals, has previously been shown in dogs even upon solely hearing negative emotional sounds of humans or conspecifics. The current investigation further sheds light on this phenomenon by...

Determination of a safe sedative combination of dexmedetomidine, ketamine and butorphanol for minor procedures in dogs by use of a stepwise optimization method

In veterinary practice, most minor procedures such as radiographs, skin biopsies, and wound treatments require sedation. The combination of butorphanol, ketamine, and dexmedetomidine is commonly used, but the ideal dosages for this combination have not been defined. This randomized prospective...

Dog identification method based on muzzle pattern image

Currently, invasive and external radio frequency identification (RFID) devices and pet tags are widely used for dog identification. However, social problems such as abandoning and losing dogs are constantly increasing. A more effective alternative to the existing identification method is...

Translational echocardiography: The dog as a clinical research model of cardiac dysfunction

Heart disease is a major contributor to mortality and disability on a global scale. Hence, there is a need for research to improve non-invasive diagnostic techniques. Diseases in dogs with characteristics very similar to those of human pathologies hold promise...

Evaluating the accuracy of facial expressions as emotion indicators across contexts in dogs

Facial expressions potentially serve as indicators of animal emotions if they are consistently present across situations that (likely) elicit the same emotional state. In a previous study, we used the Dog Facial Action Coding System (DogFACS) to identify facial expressions...

A promising novel judgement bias test to evaluate affective states in dogs (Canis familiaris)

The judgement bias test represents one of the most applied tools to evaluate animals' optimistic/pessimistic attitude and to infer their emotional and welfare state accordingly. The judgement bias test (JBT) has been used several times with dogs (Canis familiaris), in...

Here puppy, chew on this: Short-term provision of toys does not improve welfare in companion dogs

Retail dog toys are often provided to companion animals to provide cognitive and physical stimu- lation and improve the animals' quality of life. These toys, sometimes known as “enrichment toys”, have been shown to play a role in increasing appetite...

Positive human interaction improves welfare in commercial breeding dogs: Evidence from attention bias and human sociability tests

Intensive breeding practices found in large scale Commercial Breeding Establishments (CBEs) raise significant concerns about breeding dam welfare. Large-scale CBE dams spend most of their reproductive lives confined to kennels, with limited access to enriching experiences including positive human interaction....
