Things to Keep in Mind When Training Your 12-Week-Old Cairn Terrier

If you have a Cairn terrier, the first thing you should do is start training him from an early age. This breed needs to know who is the boss and who is not. It is best to create a routine, using the same command words, and creating rules. It will also help if you make the training fun and entertaining for your dog. Here are some things to keep in mind when training your 12-week-old Cairn.

When feeding your 12-week-old Cairn terrier, keep in mind that it is a small dog and needs a good amount of food. A good rule of thumb is to feed it a one-sixth cup of dry food three times a day. As the dog grows, it will need more. By six months, your Cairn will be eating twice a day and eating one-third cup of dry food plus a generous tablespoon of meat at each feeding.


Another thing to keep in mind when evaluating your 12-week-old Cairn terrier is that he may be suffering from glaucoma, which can cause blindness in advanced cases. This painful condition is accompanied by watery eyes, redness of the eye whites, and squinting. Your dog may also experience pain in the rear legs. If you notice any of these symptoms, you should immediately take him to the vet for an appointment.

Healthy Cairn Terrier

A healthy Cairn terrier will be friendly and playful. Despite their small size, this breed is tough and athletic. They can play with larger dogs and with children. Their small size will also make them great companions. If you are unsure of what to expect, it is best to seek advice from your veterinarian before adopting a Cairn terrier. You will have many opportunities to make the right choice for your pup.

Exercise and Training

Cairn terriers need lots of exercises. A good exercise routine should include walks on a leash and some time in the backyard. A little exercise is also beneficial for the coat. It is easy to care for and maintain. A Cairn terrier’s roots go back further than Toto from the Wizard of Oz. However, their accomplishments are even greater. And while they are playful and energetic, they can also be naughty and problematic. A dog may dig up the yard or rip up your sofa.

Average Size

The average size of a Cairn terrier is nine to ten inches at the withers and 9.5 inches tall at the tail. If you are buying a Cairn terrier from a breeder who does not breed according to breed standards, you may end up with a dog that is just an inch or two short. Even if the size of the dog is a little bit off from the ideal size, the average length is around 15 inches from the front of the chest to the base of the tail.

As with any dog, Cairn terriers are prone to parasites. Although they are not particularly difficult to train, their high prey drive and stubbornness may pose a challenge for first-time dog owners. However, these dogs can be great family pets if you’re willing to spend plenty of time together and keep them active. If you want to enjoy a playful, active dog, a Cairn terrier might be the perfect match.

Weight and Height

The Cairn terrier reaches adult size and weight at about 10 to 12 weeks of age. It is also physically and sexually mature at this age. You should switch your Cairn terrier’s food gradually to make the transition easier and avoid stomach problems along the way. It is important to socialize your Cairn terrier with other dogs, as this helps them develop character traits and makes them more sociable.

At this age, you should be able to housetrain your Cairn terrier, as he is not yet leash-trained. In addition, a yard with at least four feet of fence is essential for your dog’s safety. It is important to supervise your dog whenever he is outside, as he can easily jump out of a 4-foot fence. If you have any doubts, do not hesitate to ask a professional for help.


A Cairn terrier should be spayed before he is a year old. He will have to undergo neutering before being ready for a new home. He should be spayed at least seven months of age if you do not plan on letting him live with other pets. He is also likely to have neuter deposits, so he should be neutered between six and seven months old.
