This was a fall-themed gift for our friends' large dog. He really liked it -- especially the squeaker -- and enjoyed quietly chewing on it during our visit. By the time we left, it was still in good shape. We've given their dog other chew toys, and they are usually pretty beaten up by the time we leave, but this toy still looked and squeaked fine. No telling what it looks like now, but I can definitely say it survived at least 2 days of heavy dog chewing.

Perfect Pumpkin for Rough Chewers!

Pattern Name: Pumpkin, Size: Large

This is the perfect chew toy for any larger dogs that chew rough! Wow! This thing has held up for over a month without a tear or piece torn off. Soooo durable! We have a 5 year old Boxer and she destroys most toys, not this one. She loves the squeaker and we love that she can’t get it out and destroy it! Total win. Plus, it’s cute for Fall/Halloween fun for your fur baby!
