Is it time to give up my dog?

For background I’ve had my cavapoo for about 4 years, I got her when she was a puppy and she’s just turned 4.

I’m unable to afford training for her and even with my 9 to 5 I don’t have enough time to really dedicate to any type of at home training. The biggest issue is her potty training. She only likes to go and pee outside when it’s warm and absolutely hates when it’s even a little bit cold. She also had a bit of anxiety and if she hears any type of sudden sound or loud noise, she’ll refuse to go outside and drag me back to our house. And on mornings I have work I can’t do the whole “keep her outside until she goes potty” thing without being late. So I’m at a real loss for what to do.

The thought of giving her up breaks my heart because she’s truly helped me and my mental health.

Any advice is truly appreciated and needed!
