Revealed the source, "A few days ago, Imran Khan found a brown doberman puppy in the bylanes of Pali Hill area where he resides. The sweet chap that he is, Imran actually tracked down the owner of the puppy and went to him with his lost puppy. But the owner though acknowledged the fact that it was his puppy, surprised Imran saying that he left it since he didn't want to keep it anymore. Imran then took the puppy to his own home and since then is treating it as his own pet. It's a female dog and Imran and his mom Nuzhat are enjoying its company a lot nowadays."
Imran seems to have been inspired by his mamujaan Aamir Khan in this regards as our source further revealed Aamir's love for pet, "Just sometime back Aamir Khan had found a small stray cat near his building premises and got her home. Now she is like one of their important family members."
