The Bichon Frise is a small French breed of companion dog. Although it may have originated from water breeds, most records regarding the Bichon Frise suggest that it has been kept primarily and predominantly as a companion, and it was especially popular with French nobility during the 16th Century.

The breed remains popular and one of the reasons for its popularity is that it is a small breed. An adult can weigh between 10-16 pounds and can be 9-12 inches long. It can adapt to life in an apartment, although certainly won’t complain at being given some outdoor space in which to run around, and it is considered a happy breed, although it can suffer separation anxiety and does have a slight tendency to be vocal.

Bichon Frise Breed Overview

The Bichon Frise is believed to have originated in France, although some experts argue that it was actually the Italians that brought the dog back to mainland Europe from the Canary Islands. In any case, the breed is a popular companion pet.

It is considered a happy breed that will get along with family members. It is lively and is usually always up for a game. It can be quite a lively dog, but its relatively small size means that it doesn’t require too much in the way of exercise.

The breed is intelligent, and it will need somewhere to channel this intelligence. Consider signing up for agility and training classes early in the dog’s life because this will help ensure that it has a legitimate output for its energy. It can also help to teach the Bichon not to jump up while teaching the “quiet” command can go a long way to ensuring your sanity.

One area where the Bichon does not necessarily excel is in its need to have its humans around. The breed is prone to separation anxiety and a stressed Bichon Frise left to its own devices for too long is likely to exhibit destructive and other unwanted behaviors. Those that go out to work or school all day may want to consider a different breed, or at least consider getting a regular walker.

Bichon Frise Size and Growth Chart

The Bichon Frise is a small breed that as an adult can weigh between 10 and 16 pounds. Males usually weigh a little more than females, and obviously, that is a large weight bracket that the dog can fall into. In this chart, we look at Bichon Frises at different ages so that you can determine whether your pup is on the right track or whether it is either under or overweight for the breed.

Newborn 6 – 8 ounces 5 – 6 inches
1 month 1 – 1.5 pounds 5 – 6 inches
2 months 1.5 – 2 pounds 6 – 7 inches
4 months 3 – 5 pounds 7 – 8 inches

When Does a Bichon Frise Stop Growing?

Smaller breeds tend to reach maturity and stop growing sooner than big breeds, and because the Bichon Frise is such a small dog breed, it is considered fully grown by the time it reaches about 9 to 10 months, although some may continue growing until they reach 12 months of age. The breed has a typical lifespan of 12 to 15 years and is considered senior when it reaches the age of between 7 and 10 years. Every individual dog is different and while some might become less active and really slow down at the age of 7 years, others will keep going and be lively and active dogs until they reach 10 years or more.

Factors Affecting the Size of Bichon Frises
  • Genetics – One of the biggest factors that determine how big a Bichon Frise will get is genetics, and there is nothing you can do about the genetics of a dog. If your Bichon is genetically predestined to be on the bigger end of the Bichon Frise scale, there is nothing you can do to prevent this growth.
  • Diet – While you can’t necessarily affect the height or length your dog reaches, as owner and main feeder of the dog, you do have a big impact on how heavy it will become. Ensure a balanced diet and avoid feeding too many treats to ensure that your Bichon doesn’t put on too much weight.
  • Health – Some illnesses can cause weight gain and weight loss, and some may stunt or encourage growth. If your dog undergoes a sudden weight change or you believe its growth might be stunted or exaggerated, consult your vet so they can run tests and ensure everything is healthy.
  • Age – A dog’s size can change with its age. Obviously, as a puppy gets older, it gets bigger, but senior dogs can start to lose bulk and size as they age. Again, there isn’t much that can be done about this other than ensuring a healthy diet and good general health.

Ideal Diet for Maintaining a Healthy Weight

Typically, a Bichon Frise needs between a half and a whole cup of good-quality dry kibble every day. Ensure that the kibble is a complete meal, which means that it meets all of the dietary requirements of your dog, such as protein levels as well as the inclusion of vitamins and minerals.

Alternatively, you can feed wet food, but be aware that canned food can cause more weight gain because it is higher in calories. Weigh your dog and follow the feeding guidelines on the packet. If you find your dog is putting on weight, consult a vet, adjust the feeding schedule, and move to a diet food that does not contain as many calories but still meets the daily dietary requirements of the breed.

The raw food diet has become increasingly popular. If you follow this diet plan and create all the meals yourself, it does require a lot of research and measurement to make sure you get everything right, but there is also an increasing number of companies that offer premeasured and prepackaged raw meals.

How to Measure Your Bichon Frise

To ensure that your Bichon Frise is on track and meets expected size standards for the breed, you will need to measure them regularly. To measure the height, use a tape measure and measure from the floor to the withers, which is the top of the shoulder. The expected height is usually given in inches. To measure weight, if you can’t convince your dog to sit calmly on scales, weigh yourself and then weigh yourself holding the dog. The difference between these two measurements is how much your dog weighs. This is especially useful information when determining the amount of food you should give at meal times. Your vet can also measure the height and weight of your dog for you, and this may be included as part of a checkup or consultation.

Conclusion

The Bichon Frise is a popular companion dog breed. It is a small breed that is lively, friendly, and intelligent. It will usually reach its full adult size by the time it reaches 10 months, although it may still grow a little more until the dog reaches 12 months of age. If you are worried about the height or weight of your dog, consult a vet and let them know of any other symptoms or concerns you have.
