First, I want to start by saying thank you for everyone who reached out and offered their sympathy, advice, comfort, hugs, and encouragement.
Second, at this point, I am kind of embarressed and saddened that I had written my previous post in the first place. It was a desperate time and I think I was looking for a desperate solution.
I knew it would take all the 4-leggers time to adjust to the baby, I knew there would be some acting out, maybe some withdrawl, jealousy etc... But as the weeks went by, Mack was the only one who was NOT liking the new addition - He was not taking well - AT ALL. I won't go into details, but there was a lot of growling, snipping at times, shredding of stuffed things, blankets, pretty much anything he could get his paws on, and angry pooping and peeing in the house (I say angry because Mack is 5 years old and house trained. I can't remember the last time he messed in the house and here it was happening DAILY.) To be honest, at that time, I thought Mack was a lost cause - I gave up...
The turning point: I went on the Potomac Lab Rescue website and just looking at all the pups faces on their main page waiting to be adopted really struck my heart strings. I was thinking what blurb they would write for Mack, what picture they would use, and I just couldn't even imagine someone coming to take him from me. I don't know how to explain it, but after looking at that website it renewed me - renewed my patience.
