This is the very handsome 11 month old Bowie, who first came to see me for:
- Car chasing
- Chewing household fixtures & fittings
- Inability to settle, which was worse for a couple of hours after eating
- Compulsive digging in his water bowl
- Resource guarding food from the other household dog
- Extreme arousal with jumping and biting when his owner was preparing his food
- He would also eat very quickly with great big gulps
These sorts of behaviours can often be linked to gastrointestinal discomfort, but Bowie didn’t show any of the common physical signs of this, such as diarrhoea or loose faeces, vomiting, passing wind or burping.
We implemented a behaviour plan and eliminated the car chasing and digging in his water bowl, but the other behaviours, although less intense, were still present.
So we asked the vet to test for giardia and started to think about food intolerances. Giardia is a tiny parasite that attacks the lining of the intestines and causes very watery, strong smelling diarrhoea. It can cause pain and discomfort in dogs and a wide range of pain-induced behaviours such as those we were seeing in Bowie. And with the brain-gut link that scientists are learning more about every day, it’s not surprising that an attack on the gut can completely upset behaviour.
However, giardia can be present in the absence of medical symptoms, which is why we tested Bowie. The test came back positive, and Bowie is about to end his course of treatment. Unfortunately, giardia can cause damage to the gut leading to ongoing issues, and is very easy to re-ingest causing further infections.
So although we are seeing some signs of improvement, such as his increased ability to settle after eating, it’s going to be a long road helping Bowie to recover before we start to see signs of behavioural improvement. But at least we know what is causing his behaviour and how to help him. 🙂
