Typically, you can start styling an Old English Sheepdog (OES) around ten months old. After this initial grooming, regular trims every one to two months are recommended to maintain their coat.

The ten-month mark is ideal as by then, most OES puppies have completed their vaccination schedule, making it safe for them to go out, play, and get professional grooming. However, during this "awkward" teenage phase, they are still shedding their puppy coat while their adult fur is growing in quickly. This means their hairstyles may not last as long and frequent trims are necessary. For more lasting results, it's advisable to start styling around one year old, when their adult coat is more established.
Regular grooming not only maintains their appearance, but also promotes healthy coat growth. It's crucial to avoid cutting their fur too short, as this can irritate their skin and potentially lead to various skin issues. Adjusting their diet to avoid excessive oil and salt and incorporating supplements like lecithin and egg yolks can also support a healthier and more beautiful coat. Remember, a healthy diet supports healthy skin and hair!
Generally, most pet dogs require a trim about once a month. However, the frequency will depend on how quickly your dog’s hair grows and the skill level of your groomer. If their hair grows quickly, or if the groom is not done very well, the style might not hold up for long. If the style becomes too messy and unkempt between trims, it's a good indication that it's time for another grooming session. The key is to find a regular grooming routine that works best for your beloved OES and their unique coat needs. Proper and regular grooming will keep your dog happy, healthy, and looking their best!
