Hi - we have a 1yr old ruby called Fudge. Often (more often than not) whilst walking Fudge he stops and coughs for several seconds. The actual action is difficult to explain - other than being similar to the noise/action a cat makes when coughing up a fur ball!!!! The vet has asked us to video Fudge doing this - which we've done, just waiting to book him in for a tooth removal at which point the vet is going to take the opportunity whilst he's under to investigate. Any ideas what the cause could be? We use a harness style lead so it's not pressure from collar etc. Any advice would be appreciated. Thanks
