The ISPCA has launched an emergency appeal for support because it says Ireland is swamped with unwanted dogs.
Charity inspectors have taken in almost 700 dogs in the first quarter of 2023 alone.
It says it's dealt with an 80% increase in the number of animals needing accommodation.
It says the four shelters in Wicklow, Donegal, Longford, and Mallow in Cork have reached full capacity - and it's renting space elsewhere.
CEO of the ISPCA is Dr Cyril Sullivan who said, "this is a crisis.
"We urgently need your support and help.
"The ISPCA has witnessed an unprecedented number of animals rescued from cruel situations.
"Several factors have contributed to the surge in cruelty cases encountered by the ISPCA inspectorate since late 2022, continuing into 2023.
"Key among these factors is the significant slowdown in the response to rehoming healthy dogs.
"When animals are found to be suffering, the Irish public and ISPCA supporters understand that the charity will take immediate action to ensure their safety.
"But the financial burden of providing secure housing and care for these animals has become overwhelming.
"Your support can make all the difference, animals need our help now, there is no time to waste.
"We need your support.”
