Hi,
Yes dogs do get anaemia. My 3yr JRT had it. He had very pale gums almost white most of the time, although they did pink up at times. He was also slightly quieter than normal and didn't want to walk too far.
The vet put him on iron tablets and he had weekly blood tests. Each week despite the iron he was getting worse and things were not looking good.
Then I changed his diet and within a week he was back to normal. Iron tablets stopped and his blood tests were normal. He has had no sign since and that must be a year ago now.
He does suffer with a lot of acid reflux though and I think he may have had a stomach ulcer that was bleeding.
He now has his food split into 4 meals a day and that seems to keep him under control.
He is also a very allergic dog so I have to be very careful what he eats and comes into contact with.
