I have 2 dogs. A black dog (mix/rescue) and a border collie.
The border collie is knows when I am anxious and will jump on my lap and press his body against me. My partner and I joke that he’s trying to murder me, because usually he’s also pressing his floofy neck into my face. Personally, I love it. Usually it is funny enough to break the anxiety cycle.
The other dog is a huge couch potato, but also knows when I am upset. If I am crying he comes right up to me and licks my tears and snot off my face. He lets me hug and hold him until I feel better.
Also, they get me up and out of the house. Give me an extra snuggle buddy whenever I need it. I work from home and they lay under my desks in my office most days, keeping me company.
Finally, most family dinners and holidays allow us to bring the dogs. When I am overstimulated from all the noise and people, the dog is always a ready excuse to go outside for a bit and play. When I’m not avoiding all the stimulation, having them nearby is comforting, plus give me something to focus on and interact with when I’m just over it with humans.
