Now that's some CHOMPING! =) And no toothbrush needed – they have such clean teeth!
Both my dogs loooooved the raw salmon bellies that I got for them. Sometimes I also get salmon eggs to add to their meals. Whole salmon is a bit expensive for us though.
I read that you should freeze salmon in particular for at least a month before feeding, because they're prone to a specific kind of parasite that could affect dogs.
That makes me hungry - not the fish heads :D, but the filets - yum!
I absolutely know my kids would go nuts over the fish heads. They all love salmon - well any sort of fish I've given them actually. Maine shrimp season is just wrapping up (my favourite time of year) and they've been chowing on shrimp a couple of times a week as I've been getting it so often. They sit and wait patiently until I'm done and then I give them some. Brando is a bit of a resource guarder so something as high value as fish needs to be eaten in their crates.
