Heidi Klum has got a new puppy.

The 46-year-old supermodel marked National Dog Day on Monday (26.08.19) by getting a mutt mate for her family who she has named Anton.

Sharing a sweet snap of the cute canine on her Instagram account, Heidi wrote: ''We welcome a new Member to our Familie .... please meet ANTON. #NationalDogDay #puppy #5andahalfmothsold'' (sic)''

The 'America's Got Talent' judge did not reveal what breed her dog is but many fans guessed that judging by his shaggy coat, grey muzzle and black coat that Anton is an Irish Wolfhound.

The pooch is sure to be a hit with Heidi's kids, Leni, 15, Henry, 14, Johan, 12, and Lou, 10, and her husband Tom Kaulitz, who she married in late July.

The German catwalk beauty wasn't the only famous dog lover to take to social media to mark National Dog Day.

'The Big Bang Theory' actress Kaley Cuoco took to her Instagram account to urge her 5.5 followers to adopt a dog from a shelter if they are thinking about becoming a pet owner.

Alongside a photo of her with her pampered pooch Norman, she wrote: ''In honor of #nationaldogday , here's a pic of me and Norman, the day he got his freedom ride from the shelter over 10 years ago! Fun fact, he was originally named 'Storm' because someone tied him to a pole outside in the pouring rain. When the shelter picked him up, they named him Storm. I guess they thought it went with his story. I hated the name, because of his backstory, but didn't want to confuse him by changing too much.

Hence the name NORM was born! #adoptdontshop #bestdayofmylife (sic)''
