my husband passed away a couple of months ago, my elder dog is still fretting for him. I have taken her to the vets twice, she has just completed a second lot of antibiotics for a UTI, is on cartrophen injections for her arthritis and had some carprohen for 7 days to help her limping. I bought her a coat as it is cold here now even though she is inside. She is 11 yo, I take her everywhere with me when I go out, she is just so listless and won't leave my side. At home when I let her outside she just sits at the back door waiting to go back inside, she used to follow me around when I did the gardening and hung out the washing. any advise please.
