"We did what we [could], adopted Petunia to do better than anyone else, give her everything. She is resting at peace, with every day's sunset to warm her. That is what matters most. Petunia, it is not the amount of time together, but its [effects] on the soul. You affected everyone who met you. You're forever, my old lady. I miss you so much already, sleep, my sweet angel."
While Kaley on her Instagram post wrote,
"We were so honored to love her in her final days. We love you, dear special Petunia. You are the reason we continue to save dogs just like you. And we will never stop."
According to the reports, the couple adopted a senior dog and died just eight months after Karl and Kaley's previous dog, Fiona, died.
