There is actually a recall out If you have one, you might get your money back. I have two 5 year old labs. They have been with us since they were puppies. IMHO labs are among the most loving and fun dogs one can have. They also bear constant watching.
We have had three near brushes with death and one major surgery. Unbelievable things have passed through them. In short, you have to watch active breeds like a hawk. Big dogs can shred small balls like this and most toys. My biggest lab can pop a tennis ball with one bite.
If you love'em watch 'em.
