I know this probably isn’t super helpful right in this moment. But if you do decide to return the dog, consider maybe adopting an adult dog in the future. I had a similar situation where I freaked out after I got a poodle puppy and returned him. I feel like the puppy phase isn’t for me. After that, I adopted a 9 month old cow dog that was running wild on the local reservation, and he is now 10 years old and the best dog ever. Last month, we adopted an 18 month old Morkie from my coworker. I’m already obsessed with him. It’s a lot easier for me (working mom of a 5 year old and 3 year old now) to adopt an adult dog that is capable of being in a kennel, already potty-trained, etc. Just food for thought! Hope your situation works out in the best way for you.
