My 3 year old Tarrier Mix bites at the air for no reason, or I think its no reason. He has eplisy but takes meds everyday and I don't know if he's having small episoides or if he has OCD or its cause he's has anixty. Any information would be great. Thanks
It could be a number of things unfortunately.
It could be a neurological disorder linked to the epilepsy or he could simply be trying to catch flies like KISS said.
Only your vet knows for sure sorry.
