1
Q

A
  1. HyperAdrenocoricism
  2. Hypertriglyceridemia
  3. Hypothyroidism
  4. Dental disease
  5. Systemic infection
  6. Pancreatitis

(Obesity and pregnancy too)

A

1-2%

16
Q

What is the diet of choice to treat an overweight dog with DM?

(neuro stuff)

19
Q

What concurrent condition can cause uncontrolled diabetes mellitus in mini schnauzers?

A

Hypertriglyceridaemia

20
Q

What is somogyi?

A

Low BG (hypopglycemia) → triggers release of stress hormones (cortisol, epinephrine, glucagon) → rebound hyperglycemia

A

Dogs: 24 hrs
Cats: up to 72 hrs

22
Q

A

BG taken every 2 hrs over 8-12 hrs

29
Q

When taking a BG curve on a dog, what BG levels are acceptable to send the dog home?

A

If BG remains > 150 … Then repeat BG in 1 week

30
Q

When doing a BG curve on a dog, what can be evaluated to determine if the insulin dose needs to be decreased?

A
