Every day millions of Brits look at their star signs to see what type of day lies ahead.
But did you know that your dog's personality is also influenced by their zodiac sign? Your dog could be an attention seeking Leo or a disobedient Aries.
Pet horoscopes work on the same principle as human astrology and use time, date and location of birth to create a natal chart.
Wendy Stacey, from the Astrological Association of Great Britain, says: "The natal chart, often called a birth chart, looks at the planets and their position in the signs.
"A chart can reveal a pet's likes and dislikes - and can even explain quirky character traits."
Wendy says her association has around 1,500 members. Increasing numbers of its experts now offer natal charts for animals.
Keen to find out what astrology can reveal about my own dog, I asked astrologer and dog lover Michele Knight to look at Tilly's horoscope. My dog was born on 18th July 2006 and is now eight-years-old.
"Tilly's sun sign is Cancer, she has Sun in Cancer, which means she loves being at home and cuddling," explains Michele.
How true. My dog is a Cavalier King Charles Spaniel and her favourite thing is snuggling.
"The Moon in Aries means she can't hide her emotions," says Michele. "If Tilly gets moody change her walk for extra stimulation."
She adds: "A Rising Sign of Gemini makes Tilly a fantastic communicator. You will always know what Tilly is thinking or wants, she's very vocal."
Again, this information is spot on. Tilly has different barks for various things like "go outside for a wee bark" and "more biscuits bark".
Michele adds: "With Venus in Gemini she has a taste for the finer things in life. Venus in Gemini also shows she has a great capacity for love. But she always needs to know that you're giving her 100 per cent."
This all makes my heart melt because it's so true. Now I don't feel guilty about indulging my dog like a princess.
YOUR DOG'S SUN SIGN...what it means for your own pooch.
ARIES DOGS (March 22 - April 20)
Demands attention and if ignored will become naughty. But if pampered will give affection back in bucket loads. Born leaders, they can be hard to discipline.
TAURUS DOGS (April 21 - May 21)
Likes good food and a comfy bed but can be lazy, you will struggle to shift them off the coach. Emotions can be hard to read, although their determination (if they want something) will be clear.
GEMINI DOGS (May 22 - June 21)
Domesticated, fun and full of energy. "Talks" a lot...you always know what your dog is thinking. They like to "entertain" their humans and make visitors feel welcome.
CANCER DOGS (June 22 - July 22)
Super-sensitive and if told off will retreat to their bed. Craves love and affection. Gains weight easily. Gentle - especially with children. Totally devoted to their humans.
LEO DOGS (July 23 - August 23)
Regal and acts as if in charge of the household. No-one dare challenge their authority, but also loyal and outgoing. Has a good memory - you can't get one over on them.
VIRGO DOGS (August 24 - September 22)
Super hygienic, especially likes clean bedding and enjoys having a bath. At times can appear nervous and not one for being fussed. Prone to allergies and stomach upsets.
LIBRA DOGS (September 23 - October 23)
Attractive and restless. Can also be finicky eaters that test your patience! Routine-wise, you won't be able to force them to do anything that they don't feel like doing.
SCORPIO DOGS (October 24 - November 22)
Loyal and charming with the ability to read your mind - but can be stubborn. Often annoyed by the household's other animals because they prefer to be alone. Even so, can be friendly - when it suits them.
SAGITTARIUS DOGS (November 23 - December 21)
Fun-loving dogs that like to be out and about. Healthy with boundless energy and strong nerves - no shaking at fireworks for them. But if a fight's brewing they will run a mile.
CAPRICORN DOGS (December 22 - January 20)
Well-behaved and likes to keep the house in order. Your dog adores food and is prone to weight gain, might even be possessive over their grub. Can suffer with tooth problems.
AQUARIUS DOGS (January 21 - February 18)
A gentle dog who senses your moods. Can be afraid of the dark. Sometimes, though, they like to be independent. Training them isn't easy because they have little attention span.
PISCES DOGS (February 19 - March 20)
Fine-tuned to your emotions (might even be a little bit psychic) although their own moods can change quickly. Adores water but doesn't like a change of environment - so not a pet to take travelling.
