It never gets easier, and I am sympathetic for your loss. I've had the vet put down 2 of my labs, both times in my arms - that ache hurts something fierce. I encourage you to get another, he won't replace Trigger, but life with a dog is better than life without. I have a little dropkick dog who turns 10 Saturday, and I can see the future; hoping for a few more good years.
I have had Labs for nearly 40 yrs, letting them go never gets any easier. Howerver, the misery of living without one is is worse than knowing I will have to watch them pass before I am ready. Having watched 7 Labs pass, I have never been ready.
Take a little time to get over the loss, then get another "IF" you have the time to give it the attention it deserves.
