I am truly sorry for this situation, and particularly for the pain you are going through. Even though animals are not made in the image of God as we are, many in the Church have taught that upon the Resurrection and the New Earth at the End Times, God will bring back all those animals that were dear to people, for our own happiness. So, with this in mind, I pray that you may suffer with your pet, relying on God in all ways and at all times, even if your dog should succumb. I pray for your dog’s healing, for your strength through this trial, and for the forgiveness of all your sins and your protection from all sin, all evils and all problems. I extend this prayer to all animals in the world, particularly those abused, and for those with ailing pets. I ask for the intercession of the Blessed Virgin Mary, your guardian angel, and St. Francis of Assisi, the friend of animals. God bless.
Our Father, Who Art in Heaven
Hallowed be Thy Name
Thy Kingdom Come, Thy Will be Done
On Earth as it is in Heaven,
Give us this Day our Daily Bread
And forgive us our Trespasses
As we forgive those who Trespass Against us
And Lead us Not into Temptation, but Deliver us from Evil
For Thine is the Kingdom, the Power and the Glory Now and Forever.
Amen.
