Man's best friend or fighting like cats and dogs? How to encourage your pets to get along
They say dogs are man's best friends - but how do we get our canine friends to get on with cats?
To stop your pets from fighting like cats and dogs, the solution lies in how you introduce them to each other, according to new research.
Pet owners should introduce new pets to existing animals gradually rather than immediately mixing the pets, the Dogs Trust said as part of its Generation Pup research.
The study found that factors such as the speed of introduction and a puppy's age can influence their behaviour towards household cats.
The research found that one-fifth (20.1%) of pet owners introduce their new puppy to their existing cats immediately, and some 18.9% do it in less than two hours.
But gradual introductions between puppies and cats significantly increased the likelihood of them getting along.
According to the findings, puppies introduced to cats over more than one day - particularly those younger than 12 weeks - are calmer and more friendly, which can help form a better relationship.
Dr Rachel Casey, director of strategy and transformation at Dogs Trust, said: "The advice is that it's done really gradually.
"In an ideal world, what you'd want to do is to have the cat in a situation where it can escape, it can get out of the way, so maybe somewhere high that the cat can go so it doesn't feel threatened by the puppy.
"And what you really need to teach the puppy is to be calm in the presence of the cat.
"So you want to have them introduced at a time and a place where everybody is sitting down, it's really quiet, and probably have the puppy on a lead and distract it with something, so you're doing that introduction gradually," she said.

Dr Casey added that the vast majority of dogs showed "undesirable" behaviour when first introduced to a cat, including being aggressive, chasing the feline, or playing with the cat when it did not want to play.
Less than one in 10 puppies who were introduced to cats were calm and stayed relaxed.
Dr Casey said: "The factors that were really important in whether the puppies showed the kind of behaviour you'd like - the sort of calm, relaxed behaviour - were the gradual introduction, but also if they were younger.
"So if the puppies were younger than 12 weeks of age, they were more likely to be calm and relaxed."
The Generation Pup study is the largest of its kind in the UK, with more than 9,500 puppies already enrolled, including some 4,500 puppies where there is a dog-cat interaction.
The research aims to explore how factors such as genetics, early experiences and the environment shape dogs' behaviour as they grow, by asking owners to fill out questionnaires throughout the lives of their dogs.
