The biology of social attachments: opiates alleviate separation distress

The possibility that brain opiate systems participate in the control of social affect was assessed by determining capacity of low doses of exogenous opiates (0.125-0.50 mg/kg oxymorphone, and 0.10-0.50 mg/kg morphine sulfate) to reduce distress vocalizations of socially isolated puppies....

Differential effects of person in the dog and in the human

People have marked effects on dog's heart rate, with great individual variations for different persons. Apparently people to which the dog is attached have the greatest effect upon heart rate. Replications of the animal experiments using the psychotherapist and two...

A resting platform for dog pens

After converting our dog holding facilities from commercial dog cages to pen type enclosures, it became apparent that suitable resting platforms were needed. Clear acrylic plastic was used to construct the resting platforms.

Endogenous opioids and social behavior

Evidence for the hypothesis that brain-opioids mediate social affect and social attachments is summarized. Opiates and opioids are very effective in reducing social separation-induced distress vocalizations (DVs), in puppies, young guinea pigs and chicks, while opiate antagonists can increase DVs....

Activity and welfare in dogs

We need to distinguish between the minimum amount of exercise required to merely maintain health and well-being and the optimum level for their full physical and social development. This latter could [should] then be the standard. .... There is a...

A socialization program for laboratory-raised canines – Part 2: The puppy socialization schedule

Restriction of early experiences in pups results in increased anxiety and over-reactive behavior in the adult dog. These behavioral problems can be avoided by providing pups with early experiences involving novel stimuli and changes in environment to prepare the pups...

Some effects of limited exercise on purpose-bred Beagles

Dogs had little inclination to exercise when released alone into the [unstructured] exercise area. Regardless of the size of the [barren] cage, dogs did not exercise unless human beings were present in the room.

The effects of cage size and pair housing on exercise in beagle dogs

Dogs in the single cage size spent slightly less time moving, but they moved at a greater speed than when housed in double sized cages [probably because of the extreme confinement condition leading to frustration and possibly abnormal behavior patterns,...

Effects of primary enclosure size and human contact

Authors contend that they have shown that dogs are basically lazy. They do not like to exercise and have no particular inclination to run about an area.

Policy, program and people: The three P’s to well-being

Successful socialization of foxhound puppies was accomplished with a time investment of five minutes of 'hands-on' per puppy per week. During the bi-weekly socialization procedure, each puppy benefited from the interaction of people with the other littermates.
