The 'All of Me' hitmaker was unable to join his model wife at Spike TV's Guys' Choice Awards at the weekend because he was bringing French bulldog Penny to her new home, and the pair are thrilled to have a new addition to their household.
Chrissy told People: ''She's a little tripod. She has been abused, and we are so excited to welcome her to the family.''
The brunette beauty - who also has bulldogs Pippa and Puddy - also joked she and her spouse are ''working on'' having babies to raise alongside their dogs.
She said: ''If dogs are the starters for babies, we should have three or four babies by now.
''I like to think of ourselves as working on babies all the time. And working on getting dogs all the time.''
Chrissy recently joked she is unable to keep up with her 35-year-old spouse's achievements.
She said: ''Of course I'm proud. But at the same time, this guy - how often can you be proud of him? I actually told him this the other day - I was like, 'You come to me every single day with some high honour, another number one...' like 'Oh, we've reached number one in this country now.'
''I'm like, 'John, I can't keep up with how talented you are, and I can't keep up this excitement. I'm going to have to keep giving you crap because listen, it's getting exhausting.'
''You know how when someone just aces everything and you're just like 'Alright buddy, chill out'...it's gotten to that point now.''
'Smalls Change (Meditations Upon Ageing)' arrives in April.
The two awards have made for a great 72nd birthday present for the country music icon.
