Gah, sorry to hear 🙁 ^^ definitely ask the vet for a home visit, I did this for my last dog as she hated the vets, it was really gentle and totally un-stressful for her. It’ll be really tough, but just try to remember the good times. I found getting rid of food / bowls / etc (assuming you have no more dogs that is!) as it just reminds me of them.
I lost my best mate (kitty) 6 months ago, I still catch glimpses of him out the corner of my eye occasionally but it’s only a shoe or something stupid, and I still find myself when I come in from work looking in his chair to see where he is 🙁 just try not to be too upset if this happens to you!
