Hi all, I need help. I have had Penny for a year now and has steadily got worse aggressive with other dogs and today she has clawed and licked through a wall in my kitchen. Help

Oh dear, you must be feeling very worried! Kitty had a problem with wall chewing when I first brought her home, but in her case this was mostly down to separation anxiety. She wasn't aggressive with other dogs, but would try to nip people coming to the door, so I would shut her into the dining room until she calmed down - hence the wall chewing. I engaged the help of a dog behaviour therapist, and she helped wonderfully. With Penny the problem sounds far more serious and it seems to be escalating. I would strongly recommend getting help from a well-qualified therapist in your area. Your vet should be able to help you find a reputable one. Good luck!
