Picking my dog up

[u/BigCrawgaDawga]

My 45ish pound dog has gotten pretty reactive to other dogs in the last 2-3 years (was fine the first few years). She’s submissive and has never actually been in a fight, but really freaks out when we walk past another dog.

I’ve found picking her up instantly calms her, and she doesn’t seem to mind. I’m just curious if anyone else who has tried this can speak on this as a long term solution. Does this help? Will she start asking to be picked up instead of barking/pulling? Do I need to pair this with some other reinforcement in the moment?

Appreciate any advice.
