Hi Jessica, Maybe you and your MIL could meet for walks and or get together with your doggies at your house or hers....than you could mention a great food you found for your baby and how it has chaged the way your baby looks and poops and etc...just rave about it and how good the food is...that it may be a bit pricey but well worth it.....Good luck! I know that no dog should have to live its life in a cage..
