The OES and Bearded Collie might look very similar and some people might confuse them together, but they are definitely not identical. The Bobtail is slightly larger with average height around 60 cm, or 24 inches and weight 40 kg, which is 88 pounds. The Bearded Collie height is usually somewhere around 53 cm, or 21 inches and weight around 22 kg, which is 48 pounds.
Both breeds have long and thick coat which protects them from harsh weather. Both coats requires extensive brushing to prevent matting and tangling. The Bobtails coat probably requires little bit more grooming, since their undercoat is much denser and it is matting more. The Beardies coat is more manageable.
Traiditionally, the Old English Sheepdog has docked tail, which is why they are nicknamed Bobtail, but today, it is normal to see OES with long tail. The Bearded Collies tail is quite long.
Next to the size, you can distinquish those two breeds by the hair on the head. The Bearded Collies fur falls from the top of the forehead creating a kind of "eyebrows" over the eyes, and forms a characteristic "beard" around the mouth, which is why they are named Bearded. The OES on the other hand does not have those two features.
The temperament of both dogs is very similar. Of course, the temperament and personality can be vastly influenced by early training and socialization, but in general, both breeds make excellent active family companions who love its owners and family and are very affectionate towards them. Both are also pretty accepting to other people and animals if you introduce them properly and they are quite tolerant towards kids. But of course, you should never leave any dog breed with very young child unsupervised.
Some owners suggest, that Old English Sheepdog has higher protective nature to its owners and property, but they are absolutely okay with people you introduce to them. Again, this can be vastly influenced by early socialization.
Both breeds are very very active. Bearded Collie is a bit more active, agile and overall hyper and it needs truly a lot of exercise, but both breeds need a lot of daily physical and mental stimulation. Daily longer walks, hikes or jogs are necessary to have a healthy and happy dog in your home.
Those two breeds are also extremely trainable, which is due to the combination of the high intelligence and their love to its people. But early training with proper socialization is essential, just like with all breeds. With enough patience and consistency, both breeds are capable of learning tons of different trick and commands.
Overall, those two breeds have extremely similar personality. They are not for everyone, but if you are an active person, who likes outgoing and devote dogs, than there is a big chance, that both breeds would be a great fit for you.
In the beginning of the video i said, that both breeds are from Great Britain, but they actually have different country of origin, because the Old English Sheepdog was developed in England, but Bearded Collie is from Scotland. But originally, both dogs were used for herding purposes.
Every breed is prone to certain health issues. The Old English Sheepdog is hip dysplasia, entropion and cataracts. Bearded Collie is usually very healthy breed, but they ocassionally suffer from hip dysplasia or epilepsy. Those two breeds have different life expectancy and it is logical, that the larger Old English Sheepdog lifespan is slightly shorter, around 10 years, than the Bearded Collies 13-14 years.
