The beagle breed is one that has only really become popular in a big way as a pet and companion over the course of the last couple of decades, and for most of their history they were kept almost exclusively as working dogs. Beagles are cheerful, friendly dogs that tend to be highly social and get on well with strangers, and they can also be very vocal and prone to lots of barking and possibly howling. They thrive within a pack situation, and enjoy working with other dogs, where their excitable natures can be channelled into a useful purpose. The Cairn terrier is a native Scottish dog breed, and like virtually all terrier breeds they are lively, quick and tenacious, as well as being intelligent and easily bored. Their lively natures contribute to making them very excitable too. The Yorkshire terrier is one of the most popular small dog breeds in the UK, and they are in great demand as pets with people from all walks of life. They are loving and affectionate, and enjoy having someone around for company – and they like to curl up in the lap of their favourite people and chill out. However, they are also very lively little dogs that tend to be very excitable, and will often make their own entertainment. The Miniature schnauzer is the smallest of the different schnauzer dog sizes, and they are leggy but compact with a distinctive beard and eyebrows that gives them a rather serious expression, they are a very excitable breed as a whole, and need a lot of exercise, play, and mental stimulation to keep them happy. The West Highland terrier is a small, cute Scottish dog breed that is really popular all across the UK, West Highland terriers are as a whole a very excitable breed, and this is often most pronounced in younger dogs – although they tend to keep a youthful outlook on life well into old age. The fox terrier is yet another terrier breed that merits inclusion within the six most excitable dog breeds overall, and as their name suggests, the breed was originally kept and bred for working purposes, flushing out foxes when hunting with hounds, they are widely known as a “busy” breed, always looking for something to do, and they also tend to be quite vocal and prone to barking a lot when excited – which is a lot of the time.
