AceShowbiz - Animal lover Ellen DeGeneres has given America's stray pets a Christmas boost by teaming up with bosses at dog food firm Halo to deliver one million meals to unwanted pooches. The comedienne and TV personality launched a campaign to raise awareness about pet adoption with Halo bosses earlier this year and now she's making sure dogs awaiting homes get a good meal this Christmas.

She says, "At Halo we want to promote healthy living for pets and good food is a big part of that. So, we agreed to donate one million meals of Halo to shelter pets. I mean, imagine, an animal in a shelter, in a cage, lonely - a good meal is kinda all they have to look forward to, until you adopt them!"
