..where can I find more about it? Having seen a mention of this on another thread, I've been thinking whether this could be contributing to Cassie's recent undesirable behaviour. It does seem to me that I underestimated the effect of the phantom pregnancy on her (I know I do keep on) but it all came about at the same time. How long can trigger stacking last? I think she had too many new experiences in that time, now it's like she gets over stimulated in an instant. Any new place seems to be more than she wants to deal with -- and yet last year we were out every weekend doing the things we do, country shows etc, and she seemed to take it in her stride. I'd be interested to know peoples thoughts.
@selina27 here's a short article on trigger stacking which may help https://canineprinciples.com/reactive-dog-trigger-stacking/ There is also a video on YouTube by Donna Hill that may help
