How Big Will My Cairn Terrier Be When It’s Fully Grown?

Dogs are individuals and achieve different heights and weights. A large part of this is decided by their genes – if their mother and father are large then you are more likely to end up with a larger dog. However, other factors also play a role including diet and whether you have them spayed/neutered. The breed is registered with the American Kennel Club. The breed standard requires males to be 14 pounds in weight and females to be 13 pounds. Also, males should be 10 inches in height to the withers but females should be 9.5 inches.

that males are between 16.5 and 19.5 inches at the withers and females are between 15.5 and 18.5. Males should weigh between 28 and 35 pounds and females should weigh between 24 and 31 pounds.

When Should My Cairn Terrier Be Spayed or Neutered?

Because cairn terriers are small dogs, they avoid some of the problems associated with early neutering that larger breeds may experience. That said, the best age to have the procedure done depends on their breed, size, and gender. Discuss the options with your vet. As a rough guide, many small dogs are spayed/neutered at around six to nine months.

When Should My Cairn Terrier Be House Broken?

The advice from experienced Cairn terrier owners is that this breed can be stubborn with big personalities so housebreaking can be a challenge. The best approach is to learn to interpret your pup’s body language. When they look like they are going to pee or poop, take them outside and praise them. Never raise your voice when they have an accident, this will only make things worse.

When Should My Cairn Terrier Stop Eating Puppy Food?

Cairn terriers are classed as a small breed and according to the American Kennel Club, they can transition to adult food at between eight and 12 months. More energetic dogs may benefit from remaining on puppy food a little longer. You should take between seven and 10 days to transition onto a new food. Do it gradually to avoid stomach upsets. Pups usually have three meals a day but adult dogs need only one or two.

When Will My Cairn Terrier Start Losing Teeth?

Cairn pups usually start to lose their teeth at around four months of age. They should have a complete set of adult teeth by around six months but the canine teeth may take a little longer to fully emerge.

When Should I Start Training My Cairn Terrier?

You can start training your Cairn pup as soon as you bring them home at around 10 weeks. You will need plenty of treats and break up training into very short sessions. Training should start inside the home where there are very few distractions.

What Cues Should I Teach My Cairn Terrier First?

This breed is an independent working dog and that can result in challenges when training. Cairn pups can be quiet but do not be fooled! They are highly observant and will notice tiny changes and movements – they are vermin hunters after all. This also means that they will give chase so a rock-solid recall command is vital to keep them safe. You can start working on this as soon as you bring your pup home. They also need to be taught to ‘heel’ so that they will walk politely on the leash by your side.

When Will My Cairn Terrier Calm Down?

Cairn Terriers do not have a reputation as a calm dog! If you check out the online Cairn terrier forums they are full of owners asking when they can expect their energetic ‘crazy’ pup to calm down. Every dog is different but many experienced owners say that there is often a change in their energy levels after their second year.
