"A HUGE thank you to @wagmorpets for the incredible work you do. Grateful you take such great care of these rescues and find them their forever homes🙏🏼," she added.

"Chesterfield, have you fallen asleep with your bone in your mouth? I think you have!" Aniston says quietly in the clip.

Aniston is also dog mom to Clyde, a schnauzer mix, and Sophie, a white pit bull.

In the September issue of InStyle, the Murder Mystery star gushed over her dogs. "Sofie doesn't care about toys. Clyde has an obsession with toys … he buries them all over the property. Then Chesterfield came along, also with the love of toys, and it was war," she said, noting that Lord Chesterfield has "rocked our worlds" since he arrived.
