Dog breeders have long been touting the benefits of being able to raise their dogs to be fitter and healthier.
That is why many dog owners have been taking their dogs on walks or outings with them.
But new research published in the journal Applied Animal Behaviour Science shows that some dogs that are raised to be more energetic are actually more likely to be euthanized than others.
In their study, researchers at the University of California, Berkeley found that when it came to predicting whether a dog would become aggressive or adopt a more aggressive stance, the more energetic a dog was, the higher the likelihood that the dog would be euthaized.
In the study, the researchers trained 20 dogs to run at a speed of one kilometer per hour, and asked them to hold on to the tail of a toy train when they were given two options: a stop sign or a red light.
The experimenters then asked the dogs to wait 10 minutes for the stop sign to come up.
The dogs that were the fastest were the ones that would get a red-light, the team said.
This is what led the researchers to conclude that “dogs that can run faster than this are more likely than others to have dogs euthanize.”
The researchers then conducted a follow-up experiment that allowed them to test the dogs’ speed, agility, and personality.
They found that the dogs that had more energetic dogs were significantly more likely that they would be given a stop-sign than the dogs whose energy levels were in the middle.
This is how the researchers measured the dogs personalities.
The dogs were randomly assigned to one of three groups.
The first group had the energetic dogs, and the second had the calm ones.
The third group had neither energetic nor calm dogs.
The researchers then measured the level of aggression.
In addition, the dogs in the energetic group were more likely at first to bite.
This was the first time the researchers had measured the aggression of dogs that have been raised to become more energetic.
After the dogs were in training, the scientists gave them some training.
They told the dogs what the speed at which they could run was.
For example, the faster a dog ran, the less likely they were to bite at that speed.
After two weeks, the trainers gave the dogs the option of continuing training.
The energetic dogs received training at a faster pace than the calm dogs, the research showed.
This made them more likely, in theory, to keep going with the training.
The scientists then asked how the dogs responded when they ran a certain distance.
For the calm and energetic dogs the speed was the same as for the slower dogs, but for the energetic one the speed increased, and so did the aggression.
The researchers found that a dog with an energetic temperament was more likely not to bite, and a dog that had a calm temperament was less likely to bite than the other two groups.
These results suggest that the more energy the dog has, the greater its likelihood of biting, the study found.
The authors suggest that energetic dogs are more aggressive than calm ones, and that this can be explained by a higher level of energy in a dog’s body.
The higher the energy level, the easier it is for a dog to keep running at a high pace, which makes it easier for them to get their energy levels up.
“I think the reason that we found that energetic behavior is higher in energetic dogs is because they’re more energetic,” said lead author Dr. Emily Tew, an associate professor of animal sciences.
Tew, who studies energy metabolism in dogs, said the findings point to the importance of having dogs that can maintain a high level of physical activity.
“It’s a combination of physical, cognitive, and social needs that makes a dog an active dog,” Tew said.
The findings of this study suggest that it may be possible to increase the energy levels of a dog, but only when that dog can maintain it for long periods of time.
“We don’t know what exactly causes that,” Tews said.
“What we can say is that when we breed a dog it’s important to have a dog who can maintain high energy levels for longer periods of duration.”
