If Miley Cyrus is famous for adopting pets, including a pig, her friend Justin Bieber is mostly in news for abandoning them. The Canadian-born singer has reportedly abandoned his pet puppy Karma and left her with a dog trainer for more than nine months now. Justin's father Jeremy Bieber gave the pup to a trainer named Trevor Dvernichuk but never bothered to get her back, according to several media reports.

The 20-year-old singer has also failed to pay for the upkeep of the female pup and is also not returning Dvernichuk's calls regarding this, The Sun reports. The angry dog trainer from Ontario, Canada also posted furious messages on his Facebook account to get Bieber's attention in September this year but to no avail. "Karma is gonna bite you in your a-- biebers," wrote Dvernichuk on his Facebook page, according to the website. He also posted a YouTube video that dates back to a time when Bieber was excited about getting this American bull dog, in Dec. 2013. The pop singer bought the pup from Ruffin's Pet Centre in Stratford, Ontario, reveals the website.

Dvernichuk described Karma as "the best behaved American bulldog" he has ever trained. The trainer is upset with Bieber over his act of carelessness. "This is like taking your kid to school and not picking it back up," said Dvernichuk to the website.

Justin and his dad showed a lot of excitement last year when they got the puppy home and asked their fans on Twitter to suggest name for the pup. Justin's dad asked fans of his son to suggest names for the cute pup and the "Karma" was finally selected.

Justin Bieber's abandonment of pets has actually become a habit for him. The ex-boyfriend of singer Selena Gomez also had a hamster that he voluntarily presented to a fan during one of his concerts and asked her to take care of him. The "Baby" hit maker was also spotted with a Capuchin monkey sometime back but the pet was taken away from him when he did not take care of his vaccine dose.

In comparison to Justin, his friend and fellow pop star Miley Cyrus sets an example for others by showing her caring side for her pets. The songstress often posts pictures of her dogs on her Instagram profile and was extremely disturbed when one of her dogs died recently when she was on a tour. Miley even inked a permanent tattoo in her pet's memory.
