An international team has used the CRISPR gene-editing tool to modify a key gene for the replication of the classical swine fever virus in pigs. The experiment, conducted on four animals, showed complete protection against the disease. According to the researchers, this breakthrough could serve as an additional method for controlling this type of virus, which entails significant economic and animal welfare costs. The results are published in the journal Trends in Biotechnology. 

Puppies that suffer traumatic experiences are more likely to be fearful or aggressive in adulthood, according to a study published in Scientific Reports. The analysis is based on data from nearly 4,500 dogs whose owners completed a canine behaviour assessment questionnaire. The authors analysed correlations between behaviours, such as biting or retreating, and early experiences of abuse or neglect, and found that some breeds are more resilient and others more vulnerable. 

The impact of animal abandonment goes beyond the pets who suffer it, it is a public health, safety and funding issue as well. Although there have been some improvements in recent years, the experts consulted agree that the system continues to fail. In this guide, we analyze what has changed, who does this issue affect, and what must be improved.

In an anonymous online survey of dog owners in Denmark, 38% of respondents said they administered cannabinoid products - such as cannabidiol drops - to their pets without a prescription, even though their use is not legal in animals. Reasons given included pain, behavioural problems and allergies in their dogs. Some 2,000 people responded to the survey, the results of which are published in the journal PLoS ONE.

Since the first case of epizootic haemorrhagic disease (EHD) in Spain was detected in cattle in November 2022, it has spread among farms in several autonomous communities in dozens of outbreaks. The mosquito-borne disease does not affect humans, but has the potential to cause economic losses.
