Mine are holding up great. Birch and Celtic play with them every day. 1 I got in Aug and 1 in Jan and both are in great condition even with Birch the shredder. Birch for a sheltie is pretty destructive. I am sure a Lab or seriously destructive dog could do more damage.
Thanks Dr. Shelli! I wouldn't go as far as to call Callie destructive -- but most plush toys only manage to last about a month with her before she has them de-squeaked. I've been buying the stuffingless ones so she can't destuff them too. Guess I'll have to try one of these and see how she does with it.
