Experts settle debate on 7 common dog myths - including if waggy tail means happiness

Dogs are often seen as beloved members of the family. But despite being one of the UK's most popular pets, many owners still struggle to understand what their dogs are really thinking or feeling.

From tail wagging to how much exercise they need, there are lots of long-held beliefs about dogs, but not all of them are true. Now, experts from leading animal welfare organisations have spoken to the Express to set the record straight on some of the most common dog myths.

It's easy to think that a wagging tail is a sign of a happy dog, but that's not always the case.

Lindsay Arliss, behaviour and training specialist at Woodgreen Pets Charity, said: "Tail wagging has many meanings: excitement, apprehension, anticipation, even appeasement, and a vibrating tail can be a precursor to aggression."

She added: "Look at the dog's whole body. If the body, face and ears are soft, you're probably in the presence of a dog who is relaxed and social.

"But any tightness or stiffness could mean the dog is unsure or unsafe."

While some dogs might need a coat to keep warm in winter, experts say fashion clothing isn't the right choice.

Alice Holloway, Behaviour Officer at the Dogs Trust, said: "Dogs are our best friends and part of the family; they are not fashion accessories.

"Dog clothing could result in your dog overheating or stop them from expressing normal behaviour."

Lindsay agreed, adding: "Putting a dog in a fancy dress outfit can cause stress, restrict movement, and affect their ability to communicate. Clothing should only ever be for their benefit."

When a dog doesn't listen, some owners assume they're being difficult, but the truth is often more complex.

"Stubbornness is a rare trait in dogs," said Lindsay. "If your dog doesn't respond, it may be down to a lack of training or understanding.

"Sometimes, they just need time or might be feeling discomfort. Always rule out pain, especially in large breeds."

She added: "Teenage dogs can also appear less responsive. Their brains are still developing, so patience is key."

Many owners believe shaded walks are fine in summer, but even cooler spots can pose a risk.

Lindsay explained: "Even shady areas can be too hot, leading to a real risk of heatstroke and burnt paws.

"Once temperatures reach 20C, extra care is needed, especially for flat-faced breeds or older dogs."

She said to use the back of your hand to test surfaces: "If it feels hot to you, it's likely too hot for your dog."

This myth stops some people from even considering adoption, but it's not true.

Emma Wakefield, the Head of Operations at the Dogs Trust, said: "We also get puppies handed over to us, as well as dogs born in our care that need rehoming.

"While demand for puppies is high, we encourage people to also consider older dogs who have been with us longer."

Victoria Phillips, Veterinary Surgeon Manager at the Dogs Trust, warned: "Even leaving a window open won't prevent heatstroke. Disasters can happen quickly if you're delayed."

She added: "Dogs can't regulate their temperature like we do. There is no safe amount of time to leave them in a hot car."

Alice Holloway said this one is also false and "it's a common misconception".

She added: "Greyhounds usually prefer short bursts of activity and daily walks, and then they're happy to curl up on the sofa."
