Big dogs can be very loveable, but if you're considering getting one of your own always be sure you can meet its needs. Giant breeds need a good amount of space, are usually very strong and can be expensive to care for as well, so always do your research well before taking on a dog.

One way to see if a giant breed would work for you is by looking for a big dog to borrow. Or would you like your dog to go on extra walks with local dog lovers? Then sign up to BorrowMyDoggy today.
