In the behaviour section (which is a great idea) I see there are only a few choices, I would like to see an extra one, maybe the word 'fussy'
for dogs that aren't good, aren't bad, aren't aggressive, but just are a bit of a pain/fussy, ie won't stay still, sits down all the time, fussy when trying to do feet etc - or a word that could cover that

incorporate google maps or similar, so mobile dog groomers can plot on map the locations of clients to group together clients who live in same neighbourhoods.

I am pet sitting some rats but had to add them in as cats as I could only pick cat or dog from the type of animals drop down box when adding a new breed.

In schedule it would be useful to have a 12 month calendar pop up/drop down, as you would see at the bottom of a traditional diary. This would allow for a quick and easy way of booking appointments in advance. When a client asks for an appointment in say 6 weeks or 8 or 10 etc. When running a traditional diary this method was used on most appointments made.
