St. Bernard lab mix (Riverside)

I have a 3 year old St.
Bernard lab mix.
She’s very tall and has huge paws.
She’s very docile around the family but needs a home with a tall fence bc she will clear a chain link fence with no problem.
She gets along with my other dogs and cats.
She can be a little skiddish around new people but warms up very quickly.
She has a deep bark that will scare off any intruders and is extremely loyal and loving.
I have 4 dogs and she’s the escape artist and I can’t afford new fencing for my huge yard.
This is her only downfall.
She is free to a loving home with a privacy fence.
