Traits of drug and explosives detection in dogs of two breeds as evaluated by their handlers and trainers
Contributor(s):: Adamkiewicz, E., Jezierski, T., Walczak, M., Gorecka-Bruzda, A., Sobczynska, M., Prokopczyk, M., Ensminger, J.
Police dogs handlers' and trainers' opinions on Labrador retrievers (n=87) and German shepherds (n=96) trained for drugs vs. explosives detection have been compared. As most important traits in both specialties the responders indicated: (1) willingness to sniff objects, (2) concentration...
Pain-suppressed behaviors in the red-tailed hawk ( Buteo jamaicensis)
Contributor(s):: Mazor-Thomas, J. E., Mann, P. E., Karas, A. Z., Tseng, F.
Our ability to provide analgesia in wild and exotic patients is hampered by a lack of species-specific information on effective drugs and protocols. One contributing factor is the difficulty of applying data from traditional laboratory tests of nociception to clinical conditions frequently...
The effects of drug detection training on behavioral reactivity and blood neurotransmitter levels in drug detection dogs: a preliminary study
Contributor(s):: Riva, J., Marelli, S. P., Redaelli, V., Bondiolotti, G. P., Sforzini, E., Santoro, M. M., Carenzi, C., Verga, M., Luzi, F.
The aim of the present study was to analyze the effects of drug detection training on behavior and blood neurotransmitter levels in drug detection dogs so as to investigate some variables influencing dog reactivity and responsiveness to training. In all, 20 dogs were sampled out of the Guardia di...

An evaluation of serum prolactin in anxious dogs and response to treatment with selegiline or fluoxetine
Contributor(s):: Pageat, P., Lafont, C., Falewee, C., Bonnafous, L., Gaultier, E., Silliart, B.
Defining objective, reproducible and standardized parameters for the evaluation of patients is one of the main academic focuses of veterinary behaviour medicine. Prolactin, a peptidic neurohormone and a cytokine, whose main regulator is dopamine, seems to be of particular interest in relation to...
Canine fears and phobias; a regime for treatment without recourse to drugs
Contributor(s):: Rogerson, J.
From a study of 247 (102 male dogs and 145 bitches) case histories presenting varying degrees of fear and phobia, both generalised and specific, it has been possible to define standard patterns of behaviour. This was done on the basis of severity of the fear, the type of fear response displayed...
The basic neuroscience of emotional experiences in mammals: the case of subcortical FEAR circuitry and implications for clinical anxiety
Contributor(s):: Panksepp, J., Fuchs, T., Iacobucci, P.
Evidence from behavioral neuroscience strongly suggests that the unconditional (innate) capacity to experience fear, along with fear-typical patterns of autonomic and behavioral arousal, arise from specific systems of the brain - the most prominent being a FEAR circuit which courses between the...
The efficacy of three types of analgesic drugs in reducing pain in the rainbow trout, Oncorhynchus mykiss
Contributor(s):: Mettam, J. J., Oulton, L. J., McCrohan, C. R., Sneddon, L. U.
Recent research has shown the possibility of pain perception in fish; therefore, the use of analgesia or "painkillers" should be considered for invasive procedures. However, there is relatively little information on the effectiveness of analgesic drugs nor on the appropriate dose for fish. This...
A note on measurement of injection aversiveness
Contributor(s):: Grandin, T., Maxwell, K., Lanier, J.
The behavior of cattle during an injection of doramectin 1% injectable solution or ivermectin 1% injectable solution in an attempt to measure small differences in aversiveness in 61 red Angus-cross, 2-year-old heifers. Each animal was held in a squeeze chute and given a 9 ml s.c. injection of...
A review of pain assessment techniques and pharmacological approaches to pain relief after bovine castration: practical implications for cattle production within the United States. (Special Issue: Pain in farm animals.)
Contributor(s):: Coetzee, J. F.
Castration of male calves destined for beef production is a common livestock management practice in the United States amounting to approximately 7 million procedures per year. Recently there has been renewed interest in identifying methods to reduce pain associated with dehorning and castration....
Training dogs on a scent platform for oestrus detection in cows
Contributor(s):: Fischer-Tenhagen, C., Wetterholm, L., Tenhagen, B. A., Heuwieser, W.
Dogs can be trained for various odour detection tasks, and have been used to search for explosives, drugs or cancer biomarkers. However, there are only a few studies that have attempted to train dogs for oestrus detection using vaginal fluid, milk or urine of cows. In this study, seven dogs were...
Variation in stress reactivity affects cage-induced stereotypies in female CD-1 (ICR) mice
Contributor(s):: Engel, A. K. J., Gross, A. N., Richter, S. H., Rommen, J., Touma, C., Wurbel, H.
Stereotypies in captive animals typically occur under conditions that are stressful for the animals, and there is some anecdotal evidence that stress levels during early stereotypy development predict later stereotypy levels. Based on this and on the involvement of stress in the behavioural...

Effect of cholecystokinin receptor antagonists on voluntary food intake in chickens
Contributor(s):: Rodriguez-Sinovas, A., Manteca, X., Fernandez, A. G., Fernandez, E., Gonalons, E.
The effect of cholecystokinin (CCK) receptor antagonists (L-364718 and L-365260) and of diazepam on voluntary feed intake in chickens was studied. L-365260 significantly increased cumulative feed intake at 30 and 60 min, whereas L-364718 had no effect. Diazepam also increased feed intake at 30...
The use of diazepam as a pharmacological validation of eye white as an indicator of emotional state in dairy cows
Contributor(s):: Sandem, A. I., Janczak, A. M., Salte, R., Braastad, B. O.
This experiment aims at validating the percentage of visible white in the eye as an emotional indicator, related to the frustration-contentedness axis, in cattle. Earlier experiments showed that the calculated percentage of white in the eyes was larger in frustrated or scared cows compared to...
Assessing fear of novel and startling stimuli in domestic dogs
Contributor(s):: Ley, J., Coleman, G. J., Holmes, R., Hemsworth, P. H.
Dog attacks on humans are a community issue and, while defensive and offensive aggression are implicated, little is known about the motivational basis of these attacks. Defensive aggression arising from fear may be implicated in some attacks and thus research on measuring fear in dogs is clearly...
Traits and genotypes may predict the successful training of drug detection dogs
Contributor(s):: Maejima, M., Inoue-Murayama, M., Tonosaki, K., Matsuura, N., Kato, S., Saito, Y., Weiss, A., Murayama, Y., Ito, S.
In Japan, approximately 30% of dogs that enter training programs to become drug detection dogs successfully complete training. To clarify factors related to the aptitude of drug detection dogs and develop an assessment tool, we evaluated genotypes and behavioural traits of 197 candidate dogs. The...
The effect of naloxone on nursing behavior in Brahman calves
Contributor(s):: Lay, D. C., Jr., Friend, T. H., Dellmeier, G. R., Randel, R. D., Bowers, C. L., Mal, M. E., Zavala, P.
In 3 experiments in which calves were injected s.c. with saline or naloxone (at 1, 1.5 or 3 mg/kg body wt), no significant effects of naloxone on sucking behaviour were observed, although there was a tendency for naloxone-treated calves to spend less time sucking than did saline-treated calves....

Contributor(s):: Fielding, W. J., Plumridge, S.
The link between domestic violence, both at the household and personal levels, other deviant behaviors, and pet care was observed through survey responses from 641 college students in New Providence, The Bahamas. The "link" with domestic violence at the household level was found both when pets...
