 |  |  |  | Coughing during sleep is often related to a heart condition. My Belle did this from age 8 on. She had a murmur that cause fluid buildup in her lungs, which settled when she was resting and made her cough. That doesn't jibe with black spots on the lungs, though, and a heart condition can usually be heard during a routine exam.
Fish would help with flaky skin - the extra Omega 3s are beneficial for skin/fur. You can buy an O3 supplement and throw it in his dry food. It's not as good as real fish, but it's better than nothing.
If better dry food and real food is helping with the foam, there could be a digestion issue in play. It's really difficult to say, though. There are a lot of odd symptoms there. I would definitely see that specialist.
Dry food is actually very difficult to digest and derive nutrition from. Many ill or aging dogs do dramatically better on quality canned or real food for that reason. So if it's possible, keep moving toward real food. |  |  |  |  |
