I used these spells in a protection ritual for a house and its inhabitants, including the pets. In both spells, Hecate is called upon for her fierce protective attributes. I've explained the circumstances in each case, but you would want to make changes to fit the circumstances and characteristics of your pets.
To protect a dog:
The dog I wanted to protect is a beautiful, loving pet. He is also a pitbull and very protective of his family. My fear has always been that he would protect them from intruders or other harm and later be harmed himself because of the fear many people have of the breed.
Call your dog into the circle and draw a pentagram in Protection Oil on his forehead. Then recite:
"Hecate, Dark Mother
In protecting this home
In your place as is right
Stands one of your own
In defending this house
And all creatures within
Your sacred beast
Is your true loyal friend.
Keep him from harm
As he guards all he loves
And watch over him
So below, as above."
To protect a cat:
The cat in this case was a house cat who had just moved into a new house. He kept running away every time a door or window was opened.
Call your cat into the circle and draw a pentagram in Protection Oil on his forehead. Then recite:
"Moon Goddess,
I ask That you keep [name] at home
And safe from his mischief
And desire to roam.
Give him the contentment
Known to his race
And see that he's happy
In this his new place."
