When dogs are overweight or obese, it can affect their health and even shorten their lifespan significantly . So understanding the causes is important. New research from Denmark on the risk factors for dogs being heavy or obese raises questions about the role of the owner and the effects of spay/neuter surgery. The study, published in Preventive Veterinary Medicine , finds that neutering increases the risk of being heavy or obese in male dogs, but not in female dogs because they are already at higher risk. The results also suggest we need to think of overweight and obesity in dogs as a One Health issue, because the health of people and their pets is interconnected. Dr. Charlotte Reinhard

Bacteria in the anal glands of a cat are responsible for chemical signalling via poop, study shows. A Bengal cat.

Many species of carnivore use chemical signals in faeces as a way of communicating. Stinky secretions from the anal sacs, on each side of the anus, provide odours in poop that are used for chemical signals and scent marking. Wolves and spotted hyenas use these to mark territory; it is believed domestic cats do too, although this behaviour is not fully understood. Striped hyenas, spotted hyenas, and ferrets use these chemical signals to recognize other individuals. Skunks and honey badgers even use these secretions as a form of defence, and if you’ve ever met a dog that’s been skunked, you know how bad that is. Now new research from UC Davis, published in PLOS One, sheds light on how the smells

Puppies have a sensitive period for socialization from 3 until about 12-14 weeks, during which it is especially important to have a wide range of positive experiences. Many people take their puppy to puppy class during this time, but some people wonder, “Is puppy class worth it?” A new study published in the Journal of Veterinary Behaviour finds several advantages for dogs that attended puppy class when younger compared to those who didn’t. The study, by Dr. Ángela González-Martínez (Santiago de Compostela University) et al., took place in Spain and compared dogs who had completed puppy class one year earlier to those of the same age who had not taken a puppy class. The dogs were assessed using a questionnaire called the C-BARQ which wa

The benefits of nose work for ‘naughty’ and ‘reactive’ dogs By Luisa Dormer and Sienna Taylor . Photo: Luminosity-images.com/Shutterstock For many people, taking their dog to training classes is an enjoyable experience that helps to make the bond between them even stronger. For a number of dog owners, however, the thought of taking part in such activities can fill them with dread due to their dog’s ‘naughty’ behaviour. Examples of behaviours that are considered problematic include being destructive, hyperactive, straying and showing aggression towards other dogs (Wells and Hepper, 2000). Dogs that are considered hyperactive, or have a tendency to stray or run off on walks, may have strong hunt, play and prey drives. Hunt and prey drives can be defined as the dog’s innate desire to pursue, capture and kill prey, whereas a play drive is the innate desire of a dog to want to play. Dogs that display behaviour such as barking, growling, snapping, biting and lunging when they see ot

This month's choice for the  Animal Book Club  is Our Dogs, Ourselves: The Story of a Singular Bond by Alexandra Horowitz. From the book description, "From Alexandra Horowitz, #1 New York Times bestselling author of Inside of a Dog, an eye-opening, informative, and wholly entertaining examination and celebration of the human-canine relationship for the curious dog owner and science-lover alike.  We keep dogs and are kept by them.
