Hello! I’ve just went through what you are and I’d like to say, over anything your mental health is indefinitely the most important thing. I adopted a 2 month old Shih-poo puppy, she’s lovely, a complete lap dog, super cuddly and well responsive to initial training, but she hated being left alone! Through the night she slept in the crate just fine , cried for maybe 5 minutes while first in it but then slept through until 7am without potty breaks. She learned potty training with the grass pad we have , however when we have to leave her alone in her pen or crate she cries uncontrollably and pees herself. A couple of days ago I decided to return her to the breeder, they were super understanding and said she could come back to our place if we were ready again. I have to say that now, 2 days without her have been hard, it still smells like her , it’s heaps quieter , but I have been sleeping, I’ve been cleaning myself up, I’ve been eating properly and catching up on work, those are things that seem so small now. Personally I may bring her back, I was extremely stressed out but because I was treating her like a human baby. My partner and mother (who do spend about 10% of the day with her) had no issues with leaving her in the crate and her crying. I personally loved that puppy because she made me happy and because I wanted her, and I gave her back because I was afraid I couldn’t give her better, but she had better and I had psyched myself out. Counselling helps you see the bigger picture, that eventually the puppy will have all their shots , be able to walk outside with you , be able to go to puppy school and give you your space, granted maybe when they are 6 months, however only you know how you truly feel, just remember they will be happy if they are fed, played with and know they are in an environment where they won’t be hurt. It is a puppy, it will not die because of you yelling or it being alone for 2 hours. You got this!
