The United States says it has stopped sending explosive-detecting dogs to Jordan and Egypt after the deaths of a number of animals due to negligence.
"Any death of a canine in the field is an extremely sad event," a US state department spokesman said.
In September, a US report highlighted cases of negligence in the care of more than 100 dogs sent to Jordan, Egypt and eight other countries in recent years.
The US-trained dogs were provided as part of anti-terrorism programmes.
Jordan and Egypt have so far made no public comment on the issue.
On Monday, the US announced its temporary ban. The US state department official said the measure was aimed at preventing any further deaths.
The dogs "play a critical role in our CT (counter-terrorism) efforts overseas and in saving American lives," the official said.
