Hi Belinda, I love German shepherds and would be very interested in helping your family out (if you haven't already found anyone). I believe I am fit enough to be able to physically hold your dog when around other dogs. My family has also had anxious dogs so I have learnt the cues that they give when they are uncomfortable and stressed out. I would also be happy to take your dogs on separate walks so that the dog that isn't anxious can get an extra bit of socialisation. I am aware that I would need to cross the road to pass other dogs and avoid dog heavy areas when walking your german shepherd to reduce the amount of anxiety experienced by them. Once again would love to help out and also hear from you soon. (I don't have a premium account so please contact me. her conversation on my suitability)
