I have 2 dogs which are my babies! I took a empty water bottle or pop bottle (plastic) and sewed demin around them , Made it like a sleeve to fit the bottle in and sewed around the demin twice for reinforcement when the bite the the demin it crackles and the love the sound. I used old jeans you could even embroider there names on the demin I make a bunch up each year for our local animal shelter at xmas time every one deserves to be remembered at xmas time. I love animals!
