Today’s dog food is like people food in that premium varieties run the gamut from vegetarian, organic and gluten-free to anti-allergy and high-protein. Not surprisingly, these foods come at a premium and sales figures suggest that shoppers are willing to pay it. While unit sales of dog food were up 1% in the food channel, dollar sales rose 3% during that time period, indicating that higher-priced varieties are making their way to Fido’s bowl. Consumers are also buying more pet food at the drug store, perhaps due to greater availability, as members of the channel expand their food offerings. Drug stores experienced a whopping 15.5% jump in sales. Frozen and refrigerated dog foods are also gaining appeal, but dry food is still top dog, bringing in $1.8 billion in the food channel.
