Dog with tracheobronchitis and prostate problems

I apologize for very long text!!!!
The dog has a problem with his throat, when excited or running or in a state of physical activities that demand increased effort begins to cough, cough is dry, as if he had something stuck in his throat and tried to cough it out, sometimes cough out a white thick saliva, but most it is 3-5 so to speak coughing after which the condition is fine. During the walk he is much steadier, otherwise known to go up to 50 meters in front of me, as usually his wok is like slow jog and a raised tail but not now. He slowly walk next to me, tail down, it is not his classic behavior because he is dominant dog and always with the tail up and full of energy. As soon as he ran, etc. coughs. His eyes tears last 5-6 days which is also not usually particularly because i don't take him to long walks. I think even his nose is little runny because his muzzle is wetter than usual and he licks it with his tongue. Also rub his face on me, and in walks like drooling more, he usually doesn’t drool.The larynx is by my opinion redder than the rest of the oral cavity, especially the tongue. His appetite is not that good, which can be because of the fact that the less mobile. He is not a dog that loves to eat and always leave at least a little food in the bowl. But also loves dog biscuits but now it is not as appealing to him during the day only here and there in the evening or when he knows we are 're going for a walk then it like a fun. His breathing is different, as it inhales and exhales, the whole body sort to say, like breath in and breathe out. While he is doing that his mouth is closed and his nostrils are wider. Breathing is the same regardless of whether asleep or moves. Temperature is 100.4 F. I noticed that he spends more time outside or near the door (sleeping in the hallway and the door opened onto the courtyard.) few days ago I have noticed that when I came home, he coughed and rushed out and stood out as to inhale fresh air. Now since he is on essential oils and inhalation that is better and coughs is not so often. He still loves walks, and still chewing lather bones or chews his energy level is lower and it is obvious that suffers. This condition first occurred in June 2013, the same symptoms as of now, except for breathing which I don’t know, he got cough syrup did not receive antibiotics, but it took about 3-4 weeks for him to become himself. Back in February 2014, (he ate snow) cough syrup plus amoxicillin, which I gave myself and of which he was better. The cough came again around December 20 in the period when temperatures were relatively high. I think he got throat inflamed due to cold water (they like rainwater and drinks it from lake and from bucket I have, if I bring it inside they will find one that is outside…....... or is it a kennel cough that is constantly being reactivated. When symptoms began a few days syrup didn’t help I gave him klavox as vet suggested. He started klavox on 27.12 and as it was snowing I noticed on December 30. brown urine. The next day, we took him to the vet and the vet who worked because he was already on the antibiotic gave him Imizol as I found ticks and Vet concluded that it must be babesiosis even though I said it is not, because it was seven days since I found tricks and except for urine everything is ok. 2 days later we were at the vet again, did the ultrasound. In fact it has been a good two years he has occasional drops of fresh blood from the urethra but along with cough it came on a daily basis. Vet gave him nitrofurantoin. The urine cleared up, drops stopped, cough and everything calmed down to five days later drops and I have started to administer colloidal silver, dripping stopped. He was 14 days on nitrofurantoin. Few days after the last Nitrof. dose cough came back. On Sunday 25.01 I again noticed drops of blood and than few day later. The urine culture came back sterile , Prostate is slightly granular (of course the vet did not give him an antibiotic that treat the prostate inflammation although he later said when I asked again for a look that might have a slight inflammation, it is not enlarged, no cysts along the urethra too, no bladder stones either. Blood work was fine. Normal digestion, stool softer, but formed, normal color. Urinate normal (he actually urinated normal all the time). His appetite was reduced, now is better ... No problem with the anal glands and food allergies, antibiotics, vaccines. Unlike female dog more often I remove ticks from him. (we live in swamp area and walk a lot along the forest). He is prone to inflammation of the left ear (So far, three times). Psychology: The dog is very dominant protective. He does not tolerate other males especially not near me. If he meets them far enough usually nothing happens but if dog comes back toward me, he attacks. Only males no difference neutered or intact. He is highly intelligent, easy to learn, stubborn a bit. Not a dog who likes to play with other dogs or toys. Can walk for hours, not running for balls, etc. Marks his territory a lot. Cleans his paws when he comes back from a walk. Very affectionate toward me, when I’m gone for a few days on a business trip he eats half his daily amount. He likes to wriggle through the legs and sit down in front of me. He likes to lick my face (I don’t ). Always goes in before me through the door to the courtyard, the house. Not a dog who loves people, usually when someone tries to pet him he barks, especially to men, on women and children very rarely. He is a dog that has to know you first than he let it be pated and cuddle and all, Not aggressive towards people in the sense that it would bite someone. He loves to swim and in summer just to stand in the water to cool himself. Skinny.. Even little and too much. Always has been.. He is 68 at the withers cm and weighs 48 kg. When healthy walk fast. He likes to walk, plays occasional, very rarely with females he likes. He likes to get in the house when we get home from work in the evening after dinner.. Loves when I pick up the comb, he took the bone and chow while I comb him.. He cannot stand it when you try to punish him, starts to growl. He eats one meal a day 1-1.5 h after walks. Eats raw, dislike it mixed with dry food. He does not like dry food except when mixed with a can. Does not like yogurt . He likes dry cat food. If he does feel eating, will not eat. Normally leaves some food in the bowl (I think it leaves to our bitch). He loves treats (cookies) for dogs. He likes to eat bread, and other bread like food Drink plenty of water. Always over the summer I have a bottle of water if we do not go to the lake. Having trouble him eating whet there are females in heat and unfortunately there are 8 of them in 100m area. Our cats loves him a lot, so the other neighbors cats. Never had attacked feral cats.
