After searching the web for days, finally I found this forum where I guess there's a little bit of chance that someone might help me know the reason behind the sudden and untimely death of my 6 year old beloved dog.
So let me first explain to you what actually happened in details
My dog, Diego was a very healthy German Spitz and had no previous health issues. Every year he just went to the vet for his vaccinations. And then 6th of April 2015 became the darkest day of my life...He was all fit and fine till the morning, went to the roof with me for his nature's call, came back and had some water and was absolutely behaving normal as usual until around 12pm when he was on the bed and vomited right there. I've rarely seen him vomiting on the bed but this time maybe he just couldn't get down. The first time I saw him vomiting, I thought maybe it was due to some indigestion because previously when he used to eat something bad or ate more than required then he'd throw up...he threw up most of the food that he ate the other night (his regular dinner included dry kibbles of Royal Canin). after a couple of minutes he vomited again, and threw up the similar food. But this time I noticed that little bit of saliva was dripping from his mouth..not continuously just a little bit. Within an hour he had vomited about 5 times and in the last three ones most of the vomited stuff was a white-yellowish liquid. I even noticed that he was having some problem in walking. He couldn't stand still and his legs seemed a bit wobbly. I called up the vet clinic and they advised me to give him three medicines, Rantac, Zofer and Decolic, and asked me to bring him at 7pm, because that's when the doctor would come to the clinic. I quickly went to the medicine shop near my house and when I returned I saw that he had excreted some sort of a reddish-orange liquid. It was his pee. I was absolutely shocked to see this. Never in his lifetime did his urine looked like that. After giving him the medicines I gave him a mild bath to cool him down. Because the temperature in my city, Kolkata (India) is quite high and humid at this time of the year. After this his vomiting stopped but still, he looked quite week, and those little bit of saliva kept on dripping from his mouth. Once standing at a spot, it seemed that he couldn't move further. He just stood there and kept on panting. I picked him up and brought him to the bedroom and after a few minutes he slowly walked up to a spot near the bed and lied down. He was constantly panting, his tongue was hanging out as he lied and he kept on staring at the wall. I knew time was running out for him and me. There is no facility for veterinary emergency services in my city and the only option I had was to wait till the clinic opened. But it seemed that each and every second was slowly taking his life away. I just couldn't bear the sight of him in such pain. I knew no other veterinary clinic and was absolutely confused about what to do. Just as my dad came back from work at around 5pm we quickly got him into the car and was on our way to the vet. In the car I saw him taking heavy breaths and once he gave a mild stretch and kick with his hind legs, seemed like it became a bit stiff.
I still had hope that we'd be able to save him but then suddenly my worst nightmare became a reality. We were not even half the way to the vet when my diego took his last breath lying on my lap.
I suffered the biggest loss of my life on this day..I lost a loving son and a best friend. His untimely death still remains a mystery to me. Any help or clue regarding what may have happened to him would be of great help to me.
The day after diego's death I visited the vet just to get any clue about what might have happened to him. There was one lady who was a chemist, said that it might have been due to his diet, which was Royal Canin dry food. She said that the kibbles might have been contaminated with aflatoxin and maybe that was the reason behind his death. I have no idea about this. Can anyone please tell me whether this can be a reason or not?
And since that day I have been browsing the internet everyday to search for an answer and finally I found this website and even saw a similar case where a person lost his dog who died in quite a similar manner to that of diego.
Here's the link to that post : http://www.medhelp.org/posts/Dogs/Sudden-Death-of-Healthy-Dog/show/1144083
As described over there, even my diego's tongue turned purple when he died. What may be the reason for this too?
Somebody please help. I am going through the worst phase of my life.
