If your puppy is chewing, we suggest you use the SnugglePuppie only for sleep time, in your special sleep area (or during stressful, anxious moments like thunder storms, travel, Vet trips, etc) and that you observe your puppy's behavior in case he/she does chew. During the chewing phase, we suggest you remove the SnugglePuppie from your puppy's reach during the day or when you can not observe your puppy. Do not play tug with the SnugglePuppie. Be sure to use the heart beat, heater and something with the mother, littermate or someone from your household whose scent your puppy is attracted to - like something he/she pulls out of the laundry basket - the smellier the better when it comes to human scent, inside the SnugglePuppie. In our over 10 years of business, we have not had a puppy eat the SnugglePuppie to the point of being able to get the batteries or warmers out. If you leave the heart out on a table at puppy level, for example, and do not have lots of other, more interesting chew toys, it is conceivable that the puppy would chew anything reachable, especially when they are teething or left alone for far too long.
We designed the heart with a certain style of battery to be as "safe" as possible. Same with the heaters. We have nothing small to chew off on the outside of our products - we know puppies can chew. But, since we have been in business, given at the right time for the right reason (crying, loneliness, stress, anxiety, etc) the SnugglePuppie acts like a sleeping littermate, will not bite back and calms, soothes and comforts pets.
I find it so interesting that your cat chews - does your cat destroy or just knead? Cats suckle and knead, and our SnuggleKittie is the same product as the SnugglePuppie with the same safety features built-in, and therefore safe for animals.
We have worked with lion cubs, tiger cubs, bonobos (a primate), brown bear cubs, a puma, racoons, monkeys, and other potentially destructive wild animals. We have not had any one of those animals eat their SnugglePuppie or SnuggleKittie. We suggest you read our testimonials found at:
