💔

oh darling Annabelle, wish I could go back to this moment and kiss and cuddle you again... - our paths crossed through a crazy adventure and even though you were way too rocknroll cool for this soccer mom, it was always love. How I will miss your cackle laugh, your magical spirit, and curling up for tea and natter... 💔 Rest In Peace beautiful girl. Love forever, your pink poodle x

My sweet Tinky, no words can express how devastated I feel at loosing you. Sweet delicate soul, you will be sorely missed. It's impossible to comprehend that you are no longer here - we spoke on Wednesday and we planned lunch together next week and instead it's the day of your funeral. I loved you from the moment I met you, such a special friendship you and I shared which I am so grateful for. My father also adored you, and I know he will be there with you in heaven. RIP my darling friend. All our memories are treasured in the depth of my heart 💔
