I feel horrible. Truly awful. I shouted at my puppy

So I have a 7 month GSD. He’s lovely. His tempremant is to die for. He learns so quickly and he’s so loving.

Normally he will sleep at my feet whilst I’m working and we have gotten into a really good rhythm. I adore him.

We play, we walk I take him everywhere with me ( gotta keep up that socialisation and desensitisation).

I have had him since 10 weeks.

Anyway this evening I shouted at him. He didn’t particularly do anything wrong. Other than not settling. I was sat on the sofa after I had just finished work. It’s particularly busy with work right now and relentless and he just wanted a fuss. He does this thing where he nibbles my sleeves with his front teeth. We are redirecting and telling him ah ah. He does not respond to no every time he does this.

However this time he wouldn’t. I did the usual lay down. Which I get him to do every time when I am sat on my end of the sofa and we have just 5-10 mins of snuggles, cuddles and Huggles to just breath. It relaxes me.

But he would just not settle I ended up shouting lay down at him and he just looked at me with the most puppy dog eyes going and laid down and now I am just crying.

I feel truly terrible. I know with puppyhood it’s very upset and downs and ebbs and flows but I feel truly terrible.

Am I a terrible puppy mum. I love my fur babies but I dunno if I was just overstimulated from a stresful day. Or just what.

I would like to state I am Audhd and sometimes I do just get completely wound tight and can get snippety but never with my fur baby.
