Whilst we would love to spend every second of the day with our dogs, unfortunately this just isn't practical.
Many people assume that you can pop out for a full working day and just come back at lunchtime, or go to the cinema and watch a long film - but this is often far too long.
Canine behaviourist Adem Fehmi, working with natural dog food brand Barking Heads, clears up how many hours you can actually leave your dog home alone.
If you have a new puppy or a dog with separation anxiety, it's even less - which is why it's always good to have family, friends or a dog sitter to help out.

How long can I leave my dog home alone?
Adem explains: "Ideally, we should look to leave our adult dogs alone no more than four hours at a time.
"For younger dogs, they might only manage between an hour and two hours.
"Not only will your dog likely need to go to the toilet after this length of time; dogs are social mammals and need company as well as mental and physical stimulation throughout the day."
What should I do if I'm going to be out for a while?
"If you don't have any trusted family members or friends to help care for and keep your dog company in your absence, using a dog walker or pet sitter can be a good option," Adem says.
"The team at Barking Heads have created a useful downloadable guide which you can fill out, then hand over to your pet sitter so they know all the necessary info about your pup.
"If your dog has separation anxiety, a home sitter can be a good option.
"Some individual care providers might also be able to take your dog on a 1-2-1 basis at their own home if this is something your dog is able to cope with.
"Doggy day care is of course another option, which might suit some dogs over others.
"When deciding on a dog sitter, walker or day care facility, it is important to consider your dog's individual character, temperament and needs."
How can I keep my dog occupied at home?
"For me, food dispensing toys are a must," Adem says.
"Even though my own dogs are happy to be left alone, either together or individually, when I go out I always leave them with a food dispensing toy each with something tasty to work at inside.
"It is useful to ensure that the food you are offering in a food dispensing toy is valued by your dog.
"If your dog is a fussier eater, it can be helpful to save special 'high value scent' treats such as fish, meat or wet food to use.
"It is also key to choose the right food dispensing toy for your age and breed of dog.
"There are lots on the market and a behaviourist or a good pet shop should be able to point you in the right direction if you are unsure."
