Could heath problems be a reason for his bad attitude? Need serious advice?

My dogs behavior is getting worse and worse, despite all the training efforts we have put in on him. Infact he is now being nasty to our other dog and bullying her.





He has been in and out of the doggy hospital his whole life (2 years). We his owners are physically drained, mentally drained, and financially drained from his vet expenses.





He has been sick since he was a puppy. It seems once we get one condition under control he develops another.





Our dog to us it typically friendly, kind, loving, affectionate a really good dog inside these 4 walls. But get him out of these four walls and he acts terrible. And he used to love people but now he isn't friendly toward people he doesn't know.





It could be because his whole life he has been sick, and at the hospital and home resting and we get him out when we can but socialization hasn't been a big thing we've been able to do due to the fact he is always sick.





What do you think:





Also here is a current list of his health problems:





Health issues: (Some of these are conditions and some of these are things that are being looked into further)





Allergies (currently being treated for)





Breathing problems (may be related to something more)





Gastrointestinal Issues (Including Pancreatitis, where he did vomit blood several times, currently being managed and watched closely)





Severe anxiety issues (currently being treated for)





Extremely rapid heartrate





Tires easily, too easily





always panting and short of breath





Can't keep weight on. (Constant battle)





(He has been through so much tested and pretty much lived the first two years of his life in and out of the doggy hospital, its sad really)





He has some other mild conditions that are managable but those are his big issues.





Is this going to be the reality for the rest of his life? And what can we do to fix his behavior?





How do we know if this behavior is caused by pain and discomfort or something else? ThanksCould heath problems be a reason for his bad attitude? Need serious advice?
You don't say what breed, but I would be concerned for this dog. I doubt he will have any quality of life in the future and would be best in a home with adults only and probably no other pets. If that can't be arranged, you should consider euthanization.Could heath problems be a reason for his bad attitude? Need serious advice?
Wow this dog is really a mess.





I would be cranky also with all those health issues.





I think this is your reality for the rest of the dogs life.





Honestly, this dog is a candidate to be put to sleep. I would not prolong the inevitable.





At two this dog has way too many health problems. I think his quality of life has been poor and is poor. I do not believe in waiting until a dog is ';done'; to do the humane thing and put them to sleep.





I think some suffering is too much suffering.


His bad attitude tells you he hates life.
