I decide to share the symptoms Hauser had yesterday, so people who do not have experiences in dog's intestinal blockage are informed.
-refuse of food-Hauser was 100% off food
-drink water-this is something to be careful
-try to poop but have difficulty to do so
-a dog may move around to find comfortable position-Hauser was digging bush in the backyard to find a comfortable spot-this is why he was smelt bush. I think he wanted to stay outside as he felt his need to go to toilet constantly
-a dog may have usual behaviours such as barking/greeting but you can see it is struggling
-vomit-when i had the second inspection at the backyard I noticed his vomit of breakfast-this means it was something had to do dinner previous night which Hauser's case was a bone. I also noticed I could not trace any remains of bone which was unusual
-Head to tail examination-he did not appear to be uncomfortable-I walked him for 10 minutes-he walked fine
The vet detected some lumps when she examined him and x-ray confirmed those as well. The vet tried enema and worked. TG! If untreated, the gut might have been ruptured or inflamed which can lead to a serious result.
Hauser is off bone for a while and is on metamucil (sure enough, he loves it!)
Hauser is still not 100% himself but so much better than he was. I hope some information provided can help some members: i do hope nobody needs this info.
Just to add one more thing: Initially the vet considered pancreatitis (schnauzers are more susceptible towards this than some other breeds) as a possibility but quickly declined that option as Hauser was in good weight and no temperature. One of the things the vet mentioned was that we were doing well with Hauser keeping him good weight. I just need to learn to feed myself like I feed my dogs.
