[Chihuahuas] toys

[megan]

Hi everybody,
 I'm trying to find some toys to keep Valken occupied (other than play chase 
with me or my husband).  Anybody tried the toys that have them find treats? 
Some of them are pretty expensive. Anyone have a DIY solution? 
 any info would be really helpful.
 Thanks
