ISO Service Dog (Huntingdon)

I am looking for a large FEMALE dog preferably non shedding or short coated like a standard poodle, Rottweiler, Doberman, etc.
I’m not opposed to older puppies but would prefer a dog old enough that you can tell they have the temperament to be a service dog for anxiety.
They would have to be good with small children, men, other dogs, and livestock/chickens.
If they are not already trained I would get them trained for dealing with anxiety.
I cannot afford a service dog through an agency so my budget isn’t very big.
I prefer text messages and I will not be sending codes or entertaining spam.
