I am so sorry you lost your boy. There is no right or wrong timescale for grief. We all process these things in our own way and it takes as long as we need it to. Please be kind to yourself and don’t start thinking the way you are processing things is wrong or taking too long.
I lost my boy a couple of weeks after his 7th birthday, four months ago this week. I can talk about him with my family now, but was saying to dh at the weekend that, for some reason, I have been really acutely missing him over the last week and have cried over his loss quite a few times.
All sorts of things set me off. On Sunday I found the box with his favourite toy and collar and tags that I’d put away because I knew seeing them would upset dh and that really got me. I still find it upsetting to see photos and videos and they will make me cry every single time too.
I have to stop myself thinking about how we actually lost him, as he was seriously ill for a long time, but his passing was at home, sudden and quite traumatic. Even just allowing the thought of it into my head is still too much.
My other dog is an old man. He is an absolute sweetheart and a great comfort, but I still miss my heart boy so much and I am sad that he never got the chance to be a spoiled old dog.
I have had dogs for over 30 years, but for some reason his loss has hit me the hardest. Dogs give themselves to us heart and soul, with your dog you never need to have your guard up and can truly be yourself and be open and for that reason they are often the closest relationship we have.
To some extent I think it’s good to allow yourself time to sit with and process the grief, as long as it’s not completely consuming your life. If it starts to get that way then it may be time to seek some support. You mention feeling generally down as well, so it may be worth a chat with your GP or a referral to IAPT. If not Blue Cross have a pet bereavement counselling service and there are some more links that might help here.
