Yes, it is a minefield. BB is pricey, but high quality food. At the moment there are four flavours with more to come. Lamb and beef are higher in fat, chicken and turkey are lower. You can choose.
Regarding wet food, there are some good ones these days. The quality ones tend to be high in fat but as long as the right amount is given they should be ok. Portion size is key. Some have a range of flavours so the dog gets variety. As your dog is a speed eater, wet food might be useful because you could spread it out into a slow feeder.
