As with owning any animal it is important that you check on the health of your bunny daily and make note of any changes in behaviour or eating habits. When I go out in the morning and feed Dustin I always check he is alert and happy, that he comes over to say hello, that he is keen on his food and that he has been going toilet fine. Often in the afternoon when I return home from work I will check on him again, and I will also check his eyes, nose and ears are clear and clean, that his fur is clean and I check that his bottom is clean and no poo stuck there. Rabbits can be prone to fly strike if they have a dirty bottom especially in hot summer months so always check your bunny is clean down there. Dirty bottoms can also lead to infections in the genital area so check these are not red or swollen in any way. Most rabbits will keep themselves pretty clean but sometimes you need to step in and give them a bit of trim and clean in those delicate areas. It is important to get your rabbit vaccinated yearly and along with this I would take your bunny in for a yearly check up with your vet to check the condition and health of your bunny. As always advised if there is anything wrong with your bunny or change in behaviour that worries you bring them into your vet for a look. I advice finding a rabbit savy vet in your area as not all vets are that on to it about rabbits, something I have experienced with Dustin when the vet could give me little advice on his gut issues which was a bit of a waste of a check up and money. So overall just always keep an eye your bunny and check them daily and if you are ever worried take them to the vet, but if you look after your bunny well they are pretty robust and often have little health issues :)
