Roxy (GSD) is very reactive around other dogs. She acts completely OTT whioch can then cause the other dog to act either defensively or aggressively towards her. I don't believe in most cases, she would be aggressive to the other dog wonce they had met but how can I gauge this? She met my sisters 10mth old Lab at Xmas & after the intial OTT behaviour they got on brilliantly. With other non-reactive dogs she has met she has been fine with but ..... I am still worried about how she can turn quite quickly although this has only been a couple of times & it was more noise than actual bites. I am taking her to a park on Sunday where there will be alot of other dogs, we don't usually meet any on our walks which isn't helping her so I need to take the plunge. What I want to know is how close do I let her get? Should I let her get right up close? I don;t want to keep denying her access to other dogs as it will make her worse but then I am concerned about how other dog owner will react if she does snap or kick off when/if their dogs approach. I don't want to be complacent about her behaviour but then again I don't want to be too nervous & expect her to behave perfectly before she is allowed any interaction.
