High protein levels only causes unwanted hyperactivity and bad behaviour if the protein source is undigestable- i.e. from cereals rather than meat. So Applaws food has around 33% protein, but it's made up of 75% meat making it highly digestable and therefore shouldn't cause bad behaviour. When the protein comes from cereals in low quality foods (wagg, pedigree, bakers) then you can expect hyperactivity.
Our 7 month old homebred spaniel pup is currently on Burns Puppy mini which she's been on since she was 3 weeks old, soon I'll move her onto a normal Burns adult food however the Active is a good food for dogs that are slightly more 'busy' so she may go onto that if the normal adult doesn't suit her, she's a very active puppy and we have aims to either work her or do agility.
