May I ask for prayers for my dog, Annie?

I took her for her teeth cleaning yesterday and they wouldn't put her under because her heart rate was too low. Should be between 90-120, and it was 44. I've had her on Standard Process Cardio Plus & Canine Cardiac Support and whole foods supplements. It's apparently not working. I'm calling Monday to get an appointment with a doggy cardiologist, but it may take awhile to get in.

She's 13 and otherwise healthy and happy. She is my heart and soul. I'm not ready to let go of her yet, I am praying for 2 more years, of course only if she can be healthy and happy. Any prayers for her heart to heal would mean the world to me. Thank you in advance, family.

God, I come before you with a humble and contrite heart.
I am asking favor for someone else and not myself.
When you made dogs, you knew they would be our companions.
Please send Annie a Doctor with her best interests in mind.
Send her an angel to protect her, and give her comfort in times of distress. Give her full healing.
I also ask you give grace and patience to her family while they wait in hopes of finding a solution. Please give them more time, be it your will.
In your name we pray....
