Model and TV personality Chrissy Teigen and her husband John Legend have been plunged into mourning after losing their beloved English bulldog, Puddy.

Chrissy, who is also a cookbook author, took to Instagram on Wednesday (07Mar18) to share her heartache as she broke the sad news to fans.

"Today our baby, Puddy, has gone on to the pup heavens," she captioned a series of photos of their late furry friend.

"John and I got Puddy in our first year of dating, when I convinced him half-birthday presents were a real thing. 10 years ago, on May 30th, I found the dog that would be there for us through every up, down, new house, new city, new tour, new travel. He welcomed new pups and loved on new babies and new bellies. He was there for everything. Every time I needed a taste tester, someone to kiss or needed to sob into his stinky rolls, he was there."

The beauty, who is pregnant with the couple's second child, continued, "It's true what they say. We are their entire lives and it is the greatest shame that they can only bless us with a short spark of time in ours. I always knew I would lose a piece of me when he left us. I feel the hole now. I will love you forever, my boy. My heart aches. Thank you so much for everything, everything."

Chrissy had previously braced herself for losing Puddy in November (17), when the pooch was hospitalised with heart failure and had to be rushed to an animal hospital.

"At the emergency vet with my old man bulldog puddy," she posted on Twitter. "Please send him happy doggy thoughts... my first born baby".

Vets were able to save the dog and Chrissy celebrated days later as she took Puddy home: "Puddy is doing okay!!" she told fans. "The doggy gods have blessed us with hopefully many more bulldog days!!"

Chrissy and John, who are already parents to one-year-old daughter Luna, also have two French bulldogs, Penny and Pippa, as well as English bulldog puppy Pepper, who was adopted in October (17).
