Dogs are very good friends of humans. We treat them as our family member. Without them, we feel lonely. But when our best friend is not eating properly we get sick why he is not eating.
Due to hot temperature in mid-year temperature is very high. Dogs get the high temperature in the stomach. The acid level is high. They feel very upset. That is the reason why they do not eat.
So give them proper cooling in the room. Feed them curd and light food. Do not give them heavy food. Give them light food or give what they like. This will help them to get over the heat.
Dogs are very fond of eating but when summer is high they lose their appetite.
