Bearded Collie

Yes, often dramatically. Most are born black, brown, blue or fawn, then fade to a much lighter shade during the first year, sometimes to silver or cream. Many darken again between two and three years old. This fading and returning color is typical of the breed and completely normal, which is why puppy photos can look like a different dog from the adult.

The Old English Sheepdog is bigger and heavier, often 30 kg or more, with a stockier body and a distinctive rolling gait. The Bearded Collie is leaner and longer in the body, always carries a long tail and has a flatter coat parted down the back. Beardies are also more agile and generally busier, while Old English Sheepdogs tend to be steadier at home.

Usually very good. Beardies are playful, tolerant and sturdy, which suits family life. The issues are enthusiasm and herding: a young Beardie may bump small children over or nip at heels when games get wild. Supervise play with toddlers, teach children not to run shrieking around the dog, and give the dog a quiet retreat of its own.

Many pet Beardies live happily in a shorter trim, but shaving right down to the skin is not recommended. The double coat insulates against heat as well as cold and shields the skin from sunburn. A trim to around 2 to 5 cm (1 to 2 in) makes care easier while keeping some protection. Regularly removing dead undercoat does more for summer comfort than a shave.

More than many breeds. Beardies were used to move stock partly with their voice, and they still bark when excited, when greeting you or when they want something done. Early training that rewards quiet, plus plenty of physical and mental exercise, keeps it manageable. They are not ideal for thin-walled flats with noise-sensitive neighbors.
