[NAGDU] chewing

[Anne Naber]

Hi,
I just got my first guide dog; she is a yellow lab.
I'm wondering if there are any good alternative options for
chewing/staying busy, besides the nyla bones?  She'll chew on the bone
for a bit, but then gets bored with it, and she rarely chews on them.
I've tried the peanut butter one, the bacon, and the original.  She
likes the wish bone shaped ones the best.
I know she likes to chew, because she chews on things that are not
meant for chewing.
Any suggestions?
Thanks,
Anne
