Once your vet has ruled out illness and the consensus is that your dog’s loss of appetite is down to a behavioural issue, you can try several different approaches to get your dog’s taste for appropriate food back.
For example, if you’ve been hand feeding, try stopping for a while. Increase the palatability of dry food by adding a good-quality wet food. Alternatively, you can try soaking their dry food in warm water or warming wet food gently in the microwave to release its delicious aromas. Try changing their bowl too - some dogs are put off by their reflection in stainless steel or glass bowls, so try a ceramic one, and always make sure their bowl is clean.
Another idea is to give them an interactive feeding toy, which releases kibbles when they roll it around. These are good for dogs that are easily distracted by their environment.
Divide and conquer
If your family has a habit of feeding dogs with scraps from the table, they’re doing more harm than good. Your dog might not appreciate it, but you have to keep their mealtimes completely separate from yours even if this means shutting them out of the area where you eat. If you want them to regain their appetite you need to ignore their begging and praise them when they eat from their own bowl. If they refuse to eat their food, take it away after 15 minutes and offer a fresh bowl of food a few hours later. If this continues, with them still refusing to eat, contact your vet.
Remember that less is more
You could also try switching to a dry complete food designed for 'active' dogs. These formulations tend to be very concentrated, so your dog won't need to eat as much to receive an equivalent level of energy. Active foods also contain higher levels of oil, which can make them more attractive to your dog. Specially formulated 'sensitive' recipes, meanwhile, have a high level of digestibility, which can also sometimes encourage a fussy eater.
Fussy eating and your dog’s loss of appetite can be a challenging behaviour to cure, but be persistent and consistent, and you can stop it becoming a habit. Stop feeding your dog from the table and give them lots of praise for eating their own food away from the table. Finally, limit their treats to training tools only and keep their bodies and minds fit and healthy with lots of exercise, training and playing.
