Reduced heart rate variability in pet dogs affected by anxiety-related behaviour problems

We present here the first evidence of correlation between canine anxiety-related behavioural problems and heart rate variability (HRV). HRV is known to be related to a range of mental disorders in humans; however this has not been explored in dogs. Behavioural problems in dogs can result in suffering, property destruction and human injury.

What we know about the public’s level of concern for farm animal welfare in food production in developed countries

Population growth and rising consumption of meat, dairy, eggs and fish are forcing the world to face the intersecting challenges of how to sustainably feed a population expected to exceed 9 billion by 2050, while also controlling the impact of food production on the planet, on people and on animals. This review acknowledges the absence of . . . → Read More: What we know about the public’s level of concern for farm animal welfare in food production in developed countries

Abstracts: Chlamydia felis: lack of association between clinical signs and the presence of the cryptic plasmid.

Chlamydia felis is an obligate intracellular bacterial pathogen that infects cats, causing severe conjunctivitis associated with upper respiratory tract disease (URTD). In the present study, 186 cats from three non-commercial catteries in São Paulo, SP, Brazil were evaluated. The detection of C. felis was performed by PCR. The clinical severity was scored from 1 to 4, . . . → Read More: Abstracts: Chlamydia felis: lack of association between clinical signs and the presence of the cryptic plasmid.

Abstracts: Are observer ratings influenced by prescription? A comparison of Free Choice Profiling and Fixed List methods of Qualitative Behavioural Assessment

Qualitative methods of behavioural assessment use observer rating scales to score the overall demeanour or body language of animals. Establishing the reliability of such holistic approaches requires test and validation of the methods used. Here, we compare two methodologies used in Qualitative Behavioural Assessment (QBA): Fixed-Lists (FL) and Free-Choice Profiling (FCP). A laboratory class of 27 . . . → Read More: Abstracts: Are observer ratings influenced by prescription?

Abstracts: Ventricular arrhythmias in Rhodesian Ridgebacks with a family history of sudden death and results of a pedigree analysis for potential inheritance patterns

OBJECTIVE To evaluate a group of related Rhodesian Ridgebacks with a family history of sudden death for the presence of arrhythmia and to identify possible patterns of disease inheritance among these dogs.
DESIGN Prospective case series and pedigree investigation.
ANIMALS 25 Rhodesian Ridgebacks with shared bloodlines.
PROCEDURES Pedigrees of 4 young dogs (1 female and 3 males; age, 7 to 12 months) that died suddenly were evaluated, and owners of closely related dogs were asked to participate in the study. Dogs were evaluated by 24-hour Holter monitoring, standard ECG, echocardiography, or some combination of these to assess cardiac status. Necropsy reports, if available, were reviewed.
