No default constructor exists for a class

I get these errors when I run the program:

no default constructor exists for class "DynamicArray"

'DynamicArray':no appropiate default constructor available.

Could you help me out?

Repository.h

class Repository {

private:
    DynamicArray Repository_Dogs;

public:
    Repository(int capacity , int Size_Dogs_List);

};

Dog::Dog(char* name, char* breed, char* birth_date, char* vaccinations_counter, char* photograph)
{
    strcpy(this->Name, name);
    strcpy(this->Breed, breed);
    strcpy(this->Birth_Date, birth_date);
    strcpy(this->Vaccinations_Counter, vaccinations_counter);
    strcpy(this->Photograph, photograph);
}

Repository.cpp


Repository::Repository(int capacity , int size_Dogs_List)
{
    DynamicArray newDynamicArray =  DynamicArray(capacity,size_Dogs_List);
    this->Repository_Dogs = newDynamicArray;


}

DynamicArray.cpp

DynamicArray::DynamicArray(int capacity, int size_Dogs_List)
{
    this->Capacity_List = capacity;
    this->Size_Dogs_List = size_Dogs_List;
    this->Dogs_List = (Dog*)malloc(this->Capacity_List * sizeof(Dog));
}

DynamicArray.h(constructor)

public:

    DynamicArray(int capacity, int Size_Dogs_List);

Define the constructor like

Repository::Repository(int capacity , int size_Dogs_List) 
    : Repository_Dogs( capacity, size_Dogs_List )
{
}

And instead of the C function malloc use the operator new.
