Do you live in the Wyke area and have an older dog who is calm around other dogs? in Hull, East Riding of Yorkshire for sale

My dog, Mahni, is 2 years old and was rehomed with us at 4 months. When she came to us, I had a much older dog, Cloe, who Mahni doted on. When we lost Cloe in Jan of 2015, Mahni became very vocal around other dogs outside of the house. She is not aggressive, just feels the need to alert me whenever we see other dogs on our walks and despite her being very calm and obedient in the house (and having passed an obedience course at a leading dog training school) she is troublesome outdoors. If possible, I would love to find someone with a calm dog who was willing to assist me in exposure training and to start the process of getting Mahni back to her best. She is a fabulous dog but the barking raises concerns in me that she feels anxious or protective, not to mention that it can be something of a nuisance on walks. We live in the Bricknell Avenue area of Hull and most commonly walk her on the local playing fields. Any assistance would be massively appreciated as I just want the best for her and know it will take time and dedication hence me advertising for people in the area who may already be out frequently.
