Dogs can come into heat for the first time as early as 5&1/2 or 6 months, but usually the toy breeds are a bit later.
Do you plan to have Dixie spayed? Now would be a good time to do it as the health benefits from spaying are maximized if a dog is spayed before her first heat.
Did you know that a dog spayed before her first heat has only a 1% chance of developing mammary tumors as opposed to 50% in intact (non-spayed) females over age 5?
If she's licking herself a lot, you might want to have her checked for a urinary tract infection, especially if she has to pee more often.
UTI's, BTW, are more common in unspayed female dogs, too!

Spaying or Neutering Is Good for Your Pet
Spaying and neutering helps dogs and cats live longer, healthier lives.
Spaying and neutering can eliminate or reduce the incidence of a number of health problems that can be very difficult or expensive to treat.
Spaying eliminates the possibility of uterine or ovarian cancer and greatly reduces the incidence of breast cancer, particularly when your pet is spayed before her first estrous cycle.
Neutering eliminates testicular cancer and decreases the incidence of prostate disease.
Spaying or Neutering Is Good for You
Spaying and neutering makes pets better, more affectionate companions.
Neutering cats makes them less likely to spray and mark territory.
Spaying a dog or cat eliminates her heat cycle. Estrus lasts an average of six to 12 days, often twice a year, in dogs and an average of six to seven days, three or more times a year, in cats. Females in heat can cry incessantly, show nervous behavior, and attract unwanted male animals.
Unsterilized animals often exhibit more behavior and temperament problems than do those who have been spayed or neutered.
Spaying and neutering can make pets less likely to bite.
Neutering makes pets less likely to roam the neighborhood, run away, or get into fights.
Spaying and Neutering Are Good for the Community
Communities spend millions of dollars to control unwanted animals.
Irresponsible breeding contributes to the problem of dog bites and attacks.
Animal shelters are overburdened with surplus animals.
Stray pets and homeless animals get into trash containers, defecate in public areas or on private lawns, and frighten or anger people who have no understanding of their misery or needs.
Some stray animals also scare away or kill birds and wildlife.
Fix That Bunny!
When being conscientious about the pet overpopulation, don’t forget to spay or neuter your pet rabbit. Altering rabbits can reduce hormone-driven behavior such as lunging, mounting, spraying, and boxing. Spaying females can prevent ovarian, mammarian, and uterine cancers, which can be prevalent in mature does. Also, rabbits reproduce faster than dogs or cats and are the third-most surrendered animal to shelters.
Spay or neuter surgery carries a one-time cost that is relatively small when one considers its benefits. It's a small price to pay for the health of your pet and the prevention of more unwanted animals.
