1)Ok we know that at the start of march, they had the same number of dogs as in the start of january which is 25 dogs. 

2) In january 5 dogs were sold so that means that we now only have 20 dogs

3) They bought back 3 new dogs in january so that means they now have 23 dogs

4) In february 8 dogs were sold. So we do 23-8=15 dogs. They now have 15 dogs left. 

5) Now they're buying dogs so that the total number of dogs in their possession is 25 again. 25-15 is the difference needed to get back 25. 
25-15=10 dogs. They bought 10 dogs at the beginning of march.
