When Will My Rat Terrier Stop Growing?

Due to their compact physiques, rat terriers reach their full size at a relatively quick pace. A standard rat terrier is usually full-grown by the time they are 10-12 months old. The miniature rat terrier will generally stop growing even more quickly after eight months.

How Big Will My Rat Terrier Be When Fully Grown?

Regardless of whether or not you go with a miniature or standard rat terrier, these pint-sized pups stay small. A full-sized miniature rat terrier will only grow to be 10-13 inches tall and weigh 6-8 pounds. Slightly larger, the standard rat terrier grows to 13-18 inches tall and 10-25 pounds.

When Should My Rat Terrier Be Spayed or Neutered?

According to the American Animal Hospital Association Canine Life Stage Guidelines, many small-breed dogs can be altered as early as six months of age, and females should be spayed prior to their first heat. However, there are many factors to consider when deciding when to spay or neuter your dog. Speak with your pup’s breeder and your veterinarian to help determine what is best for your pooch.

When Should My Rat Terrier Start Potty Training?

Fortunately, these furry firecrackers are incredibly smart and eager to please their owners. That means you can begin potty training your new rat terrier puppy as soon as you welcome them home. As a tiny Einstein, it is likely that your rat terrier will start to pick up on housebreaking rather quickly. On average, most puppies can become fully housebroken in four to eight weeks with consistent training.

When Should My Rat Terrier Stop Eating Puppy Food?

For smaller breeds, the American Kennel Club suggests transitioning your puppy to adult food somewhere between seven and nine months of age. However, speak to your puppy’s breeder and your veterinarian to discuss the best time for your specific dog based on their growth and personal needs. When in doubt, it’s better to continue your beloved furry friend on puppy food for a little too long rather than not long enough. Additionally, take your time when transitioning your puppy to adult food. A dramatic change in diet can easily cause digestive upset in your canine companion.

When Will My Rat Terrier Start Losing Teeth?

Your rat terrier will begin losing their sharp, tiny puppy teeth around four months of age. Their pearly whites should usually be completely replaced with adult teeth by the time they are six months old. To help them during their teething stage, keep a combination of soft and rubber toys readily available for them to chew safely.

When Should I Start Training My Rat Terrier?

As mentioned before, these spunky, little terriers are quick learners. This means you can start training your new rat terrier as soon as you get them. Work with your pup in fun, short sessions throughout the day to avoid making it feel like a chore, and also encourage bonding with your furry friend.

What Commands Should I Teach My Rat Terrier First?

The first thing you should teach your rat terrier is the name game. This helps them understand that you want their attention whenever you say their name. Additionally, you can also start introducing them to basic commands such as sit, lie down, stay, and wait. Lastly, begin working on crate training and potty training, as well as acclimating them to being on a leash.
