Hello and Welcome.
Hang in there, it does get better!
You have had some very good advice here, I can only add that I found feeding him in his crate and giving him treats or filled kong when putting him in his crate and slowly building up the time has worked very well now for me.
I have had dogs all my life but always had Basset's and Clumbers. I thought I was well prepared and experienced for my little cocker boy Reese.....was I wrong! Lol
My partner works offshore and unfortunately went away for a month the day before I picked Reese (pocket rocket) up so I was on my own. I took 2 weeks off work to help settle him in and plan was to establish a routine. Lol I found the first few weeks very hard, he was on the go constantly. I had no sleep, was always on the go taking him out or cleaning up accidents, playing with him and training with things like crate and grooming trying to keep calm, upbeat and positive when I just wanted to sleep....It also did my diet the world of good as never managed more than a few mouthfuls of anything! Lol I was actually pleased to go back to work, that first morning dropped him off at my mums and kissed him goodbye and went off to work....and found myself missing that little bundle of trouble, fun and love and wishing I could win the lottery so I could spend all my time with him.
That time soon passes, take time to appreciate the cute fun times too. Reese is now 18 weeks old and a real pleasure to be with and a happy confident little boy which makes the effort and exhausting early stages worthwhile. There have been other challenges but nothing like the first few weeks.
Hope thing work out for you and pup....picture are always welcome for us to swoon over
Take care Tracy & Reese
