Bisphenol A (BPA) in the serum of pet dogs following short-term consumption of canned dog food and potential health consequences of exposure to BPA

Bisphenol A (BPA) is a widely present endocrine disruptor chemical found in many household items. Moreover, this chemical can bioaccumulate in various terrestrial and aquatic sources; thereby ensuring continual exposure of animals and humans. For most species, including humans, diet is considered the primary route of exposure. However, there has been little investigation whether commercial-brands of dog foods contain BPA and potential health ramifications of BPA-dietary exposure in dogs. We sought to determine BPA content within dog food, whether short-term consumption of these diets increases serum concentrations of BPA, and potential health consequences, as assessed by potential hematological, serum chemistry, cortisol, DNA methylation, and gut microbiome changes, in dogs associated with short-term dietary exposure to BPA.

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. Dog behaviour problems . . . → Read More: Reduced heart rate variability in pet dogs affected by anxiety-related behaviour problems

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

A tale of two terriers comes to an end

Amber_Heard_2011Deputy Prime Minister Barnaby Joyce has welcomed the conclusion of court proceedings against actress Amber Heard.
Heard was charged with violating biosecurity laws after bringing two Yorkshire terriers into the country by private jet last year while her husband Johnny Depp was shooting a film.

She was given one month good behaviour bond and no conviction, though she and Depp shot 42 second video expressing regret at the situation.

“I appreciate Ms Heard’s willingness to take responsibility for her actions last year and her acknowledgement that she broke our national biosecurity laws,” Joyce said.

“These legal proceedings reinforce the clear message I sent internationally last year that we will not tolerate disregard for our biosecurity laws, no matter who you are.”

Joyce used Facebook to share the widely mocked apology clip, which some in the media compared to a hostage video. Continue reading A tale of two terriers comes to an end

Abstracts: Assessing positive emotional states in dogs using heart rate and heart rate variability

Since most animal species have been recognised as sentient beings, emotional state may be a good indicator of welfare in animals. The goal of this study was to manipulate the environment of nine beagle research dogs to highlight physiological responses indicative of different emotional experiences. Stimuli were selected to be a more or a less positive food (meatball or food pellet) or social reward (familiar person or less familiar person). That all the stimuli were positive and of different reward value was confirmed in a runway motivation test. Dogs were tested individually while standing facing a display theatre where the different stimuli could be shown by lifting a shutter.
