Aww, I feel for you. It’s very very difficult.
You’re not mistreating the dog and it’s not as though you’ve had it a decade and are chucking it out because it’s getting on and you want a shiny new puppy. Some people need to calm down a bit with the hysterics, methinks 😂
I once got a Labrador puppy when I had an 8 year old, a 2 year old, and a newborn. Was I out of my mind? Absolutely I was. (It was supposed to be for the 8 year old, which was of course another lesson)
I did try, but he shot up to 115 lbs and didn’t listen, nipped at people, chewed everything etc. The only time he seemed truly happy was when we would visit my parents and he had 20 acres of forest to romp in and wear himself out.
In the end, after 2 years of trying, I let my parents keep him. It broke my heart at the time but 4 years on it was the best decision I could have made for all of us, including Zeke. He’s so much happier and healthier and I still get to see him.
And yes, we did eventually get another dog.
