So very sorry to hear of the loss of your loved one. She is with the Great Spirit now waiting for the day you reunite to do the things you did together again.
I feel your pain as I had a cat( I don't do cats for the most part.)that some how attached himself to my heart. He started not eatting and acting drunk this spring. I took him to the vet where it was determined he had a brain tumor that could not be removed. He was put down and I still some times find my self calling for him after close to 4 months.
I also have 4 dogs, the oldest a choclate lab 13 yrs old. she is crippled up but decideds to go on the 45 minute walk with the other 3 every evening and some times even on the morning walk. I dread the day when she is no longer with us.
Your Yellow Labby is a beautiful baby. Buy her a kong as labbies like to chew till they get about 2 years old.
