@Gelisgesti,
I'm sorry for your loss...I know how you feel...I do- because I've had two beloved dogs that had to be put to sleep. Pearl (the pictured dog) is my favorite though and I can't even tell you how hard it's been...I had to put her in a cage (for the first time) to have her flown over and she just looked at me and cried like (what are you doing to me - and why...) and she's been in quarantine since August 28th. I went to see her every week for the first four weeks, and it was fun because I met all these other dogs in quarantine with her - but I haven't been able to go in the past six weeks because I've been opening this business and I'm working like 80 hours a week.
Dogs are the best, aren't they? Have you gotten another one? I know this question might seem insensitive - but after my last one got put down - for seizures - it was so painful, I said never again, and then two years later I got Pearl and honestly - she's the best - my life would have been so much less if I'd not gotten her - which I had thought I shouldn't as I never wanted to go through losing another pet/best friend again.
