I've been buying the Zuke's puppy treats and then cutting them in half. Treats are expensive - there is a recent thread here with instructions and recipes on making your own. I am trying one recipe this week - tuna fudge!
I was using regular puppy food for treats with potty training but there wasn't anything really special about them. When I switched to using the actual treats for treats, it was a bigger deal to get the treat after going potty. I had bought Wellness soft bites and tore them in fourths, but they are fairly rich. Brodie can handle them now as special treats, but when I started using them as potty treats, they gave him loose stools. Too much of a good thing. Hence we now reserve the Wellness for really special times like when the vet comes to visit.
I found an animal sound video on you-tube. If I put it on, Brodie goes crazy over my phone. I can put it on the floor upside down so the glass is on the floor and he tries to scratch and 'attack' the case. He also will 'attack' his reflection in the glass of the entertainment unit under the tv. Sunday morning, when the 'other dog' barked at him the same time he barked, he fell over backwards in shock. They are soooo silly!
