Target has shirts, hoodies, and toys for $2.50. They also have pj's for $4.99.
I started making my own treats, because the prices got out of hand. Just one of the treats I bought for Mr. Biggs was $17 and it only lasted like 3 weeks. I also make him blankets and beds (although he prefers a pile of clothes on the floor) I also make him toys using left over fleece. When he was just a pup, I made him simple shirts out of my old ones. I just sewed them up and added decorations.
