A little brown and tan Chihuahua named Milly recently received the title “World’s Smallest Dog” from Guinness judges. Milly, often known as “Miracle Milly,” is barely 3.8 inches tall and weighs just under a pound. She is almost two years old.

Zeus, a 44-inch-tall Great Dane, is the tallest dog in the world according to Guinness Book of Records.

NBC News quotes Semler as saying about Milly, “People are amazed when they see her because she is so small.” She also has a strong personality. Her fans adore her.

When Milly was born in December 2011, she was so tiny she had to be fed through an eye dropper every two hours. As a puppy, Milly slept in a doll crib next to Semler’s bed so her concerned owner could check in on her often.

Despite her unusually small size, Milly’s signature is probably her famous camera pose. Whenever a photographer snaps a picture of the elfin Chi, she sticks her tongue out.

Sure Milly has taken the cake in this year’s Guinness race, but there are a couple of dog owners on both sides of the Atlantic who say their miniature canines could take the coveted title in the future.

Nikki Barnes, a Chihuahua breeder who lives in East Sussex, England, believes that Poppet, a 3-year-old black and brown Chihuahua, could challenge Milly’s dominance. Poppet is on pace to become the tiniest dog in the UK, according to Barnes, being less than 5 inches tall.

Barnes tells Express that “Poppet is incredibly small.” “A can of soda or lemonade is bigger than her shoulder if you put it on the floor.”

Poppet has no qualms about going up against dogs that are more than 100 times her size, despite only weighing approximately at 30 ounces (about 1.9 pounds), making her around one-third the size of the average Chi.

Barnes says about Poppet, “I have never seen her scared or back down from anything.” Regardless of their size, she always barks at other dogs and tries to challenge them.

Little Poppet loves to scamper down the pavement, and Barnes claims her dog frequently draws sizable crowds. Poppet has gained so much popularity that she will soon appear on a new British television programme that will also feature Scottish actor and comedian Ronnie Corbett.

Angel, a 5-week-old Yorkshire Terrier puppy from Alliston, Ontario, has some maturing to do because the Guinness judges will only accept canines who are at least a year old for their “World’s Smallest Dog” award. However, tiny Angel is showing she might have a chance at Guinness gold in the future at only 163 grams, or a small.36 pounds.

In his 16 years of practice, Angel’s veterinarian, Dr. Tashfeen Abbasi, claims to have never, ever seen a puppy as little as Angel.

If Angel can maintain her health, she will eventually unseat current record holder Milly, he predicts, adding, “I expect maybe we’ll have the smallest puppy.”

Due to their extraordinarily small size, the tiniest canines are sometimes referred to as “tea cups,” and they sometimes experience major, even fatal, health issues. In actuality, these “tea cup” puppies are occasionally little for the very reason that they are unhealthy.

Dr. Abbasi was initially worried that Angel, who was barely one-fourth the size of her littermates, had a congenital defect, but as the weeks pass, the Yorkie puppy is growing stronger, regaining her balance, and honing her sensory abilities. He claims she has a high chance of surviving if she can get through the next four weeks or so.

Angel’s owner Kim Passero stays up all night with the miniature Yorkie to ensure sufficient nutrition. Angel has recently progressed to eating dog chow that has been mashed up, according to Passero, who previously had to dispense the puppy’s nutrient-rich formula via a syringe.

Passero, a small-scale, self-described hobby breeder and lover of Yorkshire Terriers, claims that while she rarely breeds for “tea cup”-sized pups like Angel, it does occasionally happen.

Passero says, “I’m sure there are people out there who are doing it for the money and for the wrong reasons. We did it from the heart, therefore whatever occurs will occur.
