If u are an animal lover and are looking forward to have a pet at home, then adopting a pet is the best option rather than buying one. Thousands of street animals die every day starving out of food & shelter, human crueility adds to it more meceriable life to them.
These animals once rescued get a second life at shelter. So if u adopt a shelter animal u are a part of noble work rather than byuing puppies at breedres place where the mother dogs are forcefully pregnant and thier puppies are sold sooner to gain money.
