“We loved him so much and he brought us more happiness than we can describe.”
Molly-Mae has been posting about the unrest in the US after the killing of George Floyd.
She appeared to reference this when she wrote that there are “far, far greater issues than this.”
However, she still voiced her sadness over the loss of the dog.
She also shared that the pair were “hoping for clearer answers” from the vets as to what happened.
She added: “We just need to share this information in order to start the process of trying to accept and overcome this awful situation.”
At the same time as giving her the puppy, Tommy also gifted a Louis Vuitton dog carrier.
