My elderly dog 19 years old became very unwell 2 days ago was vomiting and retching nothing coming up appeared very weak lethargic breathing funny I took him to the vets and was told he was in a very bad way and his gums where very pale. Vet said she was concerned that we was going to lose him she mentioned various blood tests xrays etc but then said it may not be worth putting him through it and putting to sleep may be kinder I went along with putting him to sleep but now the sadness and guilt is really consuming me it keeps hitting me like a ton of bricks and the tears start I've never had such feelings of sadness and wish I could hug my dog once more and tell him how much I really loved him he was in my life for 16 years and I feel empty I wasn't expecting it to hit this badly how do I get over it and can anybody relate sorry I've posted here for traffic and I'm so upset that he's gone and ill never see him again.
