His signs are: he is barking the whole time I am gone, it makes him bark saliva all over the room I leave him in and its all under his jaw(soaked), he sometimes throws up from barking so hard and long, its like a foam, he has pooped once, he paces the whole time I am gone and when I get home, he is so hyped up from me being gone that its like he is having an asthma attack...he acts like he has ran a few miles without stopping....i noticed yesterday now that he has scartched the door..i leave paper now by each door because his saliva is in puddles sometimes and he tracks it all over the room...so he has sometimes scratched the paper, maybe even bit it, not sure....but he has never ever acted this way until about 2 months ago...he is in a laundry room that goes out to the garage....it is a pretty nice room for a lil dog and I only leave him off and on about 1/2 - 1 hour each time I go out during the day which is about 3-4 times and it doesnt matter how long i am gone he does the same thing and its started to get worse...he is started to whine while my husband is home with him and he is missing me....my husband says hes obsessed with me because he watched me all the time lol.....i am thinking of crating him while i am gone, i hope it doesnt give him a heart attack or shock him
........suggestions?????? please i need help
