My cocker spaniel -beagle mix is having seizures and is panting heavy and coughing. He has had the seizures all his life,but are more often now. Does anyone know what could be going on?

Unfortunately as all of us, including pets, get older medial things wrong with us also get worse so I suspect old age is fast catching up here with your dog and his seizures are only getting worse because of it, sorry. Contact your Vet to see if there is anything he recommends for him to help cope with everyday living. Good luck
