  1. More than noise?—Field investigations of intraspecific acoustic communication in dogs (Canis familiaris)

    Contributor(s):: Péter, Pongrácz, Éva, Szabó, Anna, Kis, András, Péter, Ádám, Miklósi

    Besides being a widely investigated behavioural phenomenon, barks of dogs often represent a factor of nuisance for people. Although some argue that dog barking has no or only minimal communicative function, it was shown recently that these acoustic signals carry various information that humans...

  2. Should I whine or should I bark? Qualitative and quantitative differences between the vocalizations of dogs with and without separation-related symptoms

    Contributor(s):: Pongrácz, Péter, Lenkei, Rita, Marx, András, Faragó, Tamás

    Separation-related disorder (SRD) is one of the most common behavioral problems of companion dogs, causing inconvenience and stress for dog owners and others living close by, as well as being considered as a major contributor to poor animal welfare. Although excessive vocalization is considered...

  3. Separation-related behaviour indicates the effect of functional breed selection in dogs (Canis familiaris)

    Contributor(s):: Pongrácz, Péter, Gómez, Sara Alvarez, Lenkei, Rita

    The domestication of dogs resulted in several fundamental behavioural changes as compared to their closest wild living relative, the wolf. While these characteristics are considered to be fairly robust across dogs, dog breeds themselves manifest apparently strong behavioural differences. Thus far...

  4. An Evaluation of Respondent Conditioning Procedures to Decrease Barking in an Animal Shelter

    Full-text: Available

    | Contributor(s):: Steven Wade Payne, Kian S Assemi

    A common problem behavior in animal shelters is excessive noise from barking, which can regularly exceed 100dBs.  Noise levels in animal shelters are correlated with increased stress in dogs, which may lead to increased problem behavior and a decrease in adoption.  The purpose of the...

  5. Judging a dog by its cover: morphology but not training influences visitor behavior toward kenneled dogs at animal shelters

    | Contributor(s):: Protopopova, A., Wynne, C. D. L.

    Currently, visitor behavior in companion animal shelters is not adequately explored. A sequence of experiments investigated how visitors interacted with kenneled dogs at an animal shelter and whether training dogs to not engage in undesirable behavior in their kennels would evoke more interest...

  6. Degree of synchrony based on individual observations underlines the importance of concurrent access to enrichment materials in finishing pigs

    | Contributor(s):: Zwicker, B., Weber, R., Wechsler, B., Gygax, L.

    Pigs are sociable animals with a strong motivation to explore and forage, and it has been stated that they have a strong motivation to do so synchronously. We examined the synchrony of exploration in groups of finishing pigs when enrichment materials were offered. We used a novel measure of...

  7. Barking in home alone suburban dogs ( Canis familiaris) in New Zealand

    | Contributor(s):: Flint, E. L., Minot, E. O., Stevenson, M., Perry, P. E., Stafford, K. J.

    The aim of this study was to establish expected average parameters for barking in normal suburban dogs in New Zealand (defined as dogs with no history of problem or nuisance barking) that are left alone for 8 hours during the day, with indoor/outdoor access, and are walked daily. Parameters...

  8. Dogs: A continuing and common neighborhood nuisance of new providence, The Bahamas

    | Contributor(s):: Fielding, W. J.

  9. Dogs can discriminate barks from different situations

    | Contributor(s):: Maros, K., Pongracz, P., Bardos, G., Molnar, C., Farago, T., Miklosi, A.

    We investigated if dogs can discriminate barks of another individual recorded in two markedly different situations: (a) when a stranger entered the property where the dog lived, and (b) when the dog was tethered to a tree and left alone. We used a habituation-dishabituation paradigm for testing...

  10. An anti-barking muzzle for dogs and its short-term effects on behaviour and saliva cortisol concentrations

    | Contributor(s):: Cronin, G. M., Hemsworth, P. H., Barnett, J. L., Jongman, E. C., Newman, E. A., McCauley, I.

    A commercial anti-barking muzzle for dogs was tested during winter on Australian Kelpies at a commercial breeding kennel, to examine the effects of the device on dog behaviour and welfare. The trial involved 16 dogs (paired on sex and age); one dog per pair was allocated at random to the Muzzle...

  11. Proceedings of a workshop to identify dog welfare issues in the US, Japan, Czech Republic, Spain and the UK

    | Contributor(s):: Houpt, K. A., Goodwin, D., Uchida, Y., Baranyiova, E., Fatjo, J., Kakuma, Y.

    The aims of this paper are first to review scientific and ethical considerations regarding the welfare of dogs in the US, UK, Czech Republic, Spain and Japan, as well as to examine research perspectives of people working within the field of applied ethology. As a guide, the Five Freedoms should...

  12. Why do pigs root and in what will they root? A review on the exploratory behaviour of pigs in relation to environmental enrichment

    | Contributor(s):: Studnitz, M., Jensen, M. B., Pedersen, L. J.

    The intention of the new European legislation on rooting materials for pigs is to improve the welfare of pigs. The question is: which materials are suitable rooting materials for pigs? To answer this question the motivation for exploration in pigs is elucidated and the needs of the pigs in this...

  13. Influence of housing conditions on Beagle behaviour

    | Contributor(s):: Hetts, S., Clark, J. D., Calpin, J. P., Arnold, C. E., Mateo, J. M.

    The effects of different spatial areas and different conditions on behaviours of Beagles maintained in a laboratory were evaluated. 18 female purpose-bred Beagles were divided into 6 groups of 3 and housed individually for 3 months each in 6 different housing conditions: (A) a 6.1 m x 9.1 m...

  14. Genetics and the development of social behavior in dogs

    | Contributor(s):: Scott, J. P.

    The puppies used in the experiments lived with their litter-mates from birth until 1 yr. of age, first in large nursery rooms and later in spacious outdoor runs. Behavioural tests were given to animals of 5 different breeds: Basenji, Beagle, Cocker Spaniel, Shetland Sheep Dog, and Wire-haired Fox...
