Dogs’ behavioral problems and their impact on the owners

Having a “problem” dog is difficult. But it’s the guilt about it that makes owners unhappy. 

A recent study has analysed why owners of dogs with behavioural problems often feel anxious or depressed. It turns out that it is not the dog’s behaviour per se that causes these feelings but rather the guilt that dog owners experience. 

Working with an empathetic and non-judgmental dog trainer, who will validate the owners distress, is therefore essential for developing a good relationship with a difficult dog.

What happens when dogs with dementia go to class together

Canine cognitive dysfunction (CCD) affects around 25% of dogs aged 8 to 12, and roughly 70% of dogs over 15. It’s the canine equivalent of Alzheimer’s: amyloid plaques, brain atrophy, disrupted sleep, disorientation, changes in social behaviour. It’s common, it’s progressive, and until recently it’s been mostly managed in isolation.

A new study from the University of Adelaide asked a different question: what if dogs with CCD went to training classes together?
Forty-two dogs, all aged 8 or older with mild to moderate CCD, took part in five weekly group sessions. Half did physical structured training: heel work, sits, recall. The other half did scent-based activities. Researchers tracked CCD severity using an established scale, measured sleep and activity using FitBark accelerometers, and also looked at something often left out of animal studies: how the people were doing.

On CCD severity, both groups stayed stable, which is itself meaningful. CCD is a progressive condition, so “not getting worse” during a five-week intervention isn’t nothing.
On sleep, the physical training group showed improvement over time. The scent group’s sleep scores declined. On activity, the scent group showed reduced peaks in the morning and evening during treatment weeks. The differences were statistically significant but with small effect sizes, so promising, but not conclusive. Five sessions is a short window.

The most striking result was also the most human one. Caregiver burden, measured using a validated scale, dropped significantly in both groups. It didn’t matter whether your dog was doing heel work or sniffing out treats. Just showing up, watching your dog engage, and being in a room with other people in the same situation was enough to reduce the burden score. 88% of participants felt better equipped to support their aging dog. 73% said they valued talking to other caregivers.

The researchers are honest about the limitations: no control group, small sample, short duration, no blinding. This is a pilot. It can’t tell us whether training slows CCD progression, that would take a much longer study with a larger sample. What it does tell us is that group training appears safe for dogs with mild-to-moderate CCD, that it may have some effect on sleep quality depending on the type of training, and that the social and emotional benefit to caregivers is real and measurable.
That last part is probably the most actionable finding right now. If your dog has CCD, finding a group – a class, a community, a forum where other people understand what it feels like.

The way we interact with dogs is human not cultural

While some believe that dogs have a unique position in western societies, it turns out that human-dog interactions are strikingly similar across cultures. In a recent study scientists went to Vanuatu, Mongolia, Madagascar, Peru, and Germany to study the bond between hunting dogs and their owners. They found that even in very different cultures and environments dog–human relationships were remarkably similar.

Cats and dogs make you less stressed, but for different reasons

Are cats or dogs the better pets? When it comes to stress reduction it turns out that they are similarly effective, but for very different reasons. While for cat owners the feeling of closeness is crucial, dog owners are mostly helped by playing, hugging and other interactions with their dogs.
